A. Cowan in The :C,I.L, Oval) By far the most precious substance marketed in the world to -day is rad- kim, The common standard of meas- urement ds by the milligram, which is once -thousandth part of a ,gram, and a gram, in turn, is a sufficiently minute unit of weight to be used in catoulat- ing the avoirdupois of .pin+heads. When, in 111312, it became apparent that Canada was moving swiftly to the dominating position as a radium producer, officials of the Dominion's Department of Mines trade some striking estimates. Beside a grant of radium, then worth $70,000, the same amount of gold was worth 70 cents. Departmental executives also esti- mated at that time that total world production of radium all told had pro- bably not reached more than 550 to 600 grants, less thee -1.a pound and a half. ,Of this, perhaps hall had, they they thought, dropped out of eMur largely as a result of it, use in lum- inous paint. They believed treed it doubt- ful if more than 2150 „rant; altogether remained available its the entire world for application M the treatment t1 cancer. lIt was a positive tact that the entire amount in all Canada, when life Dominion's dela s ' were diseov reed, was .33 to 4 grams, less than the amount which this L' MtIttry, within a fewtnontlis. tciMl the producing every 30 days) It was also trot_ that there was no producin sour:: of radium either anywhere an the American continent or anywher; within the Bri- tish Empire, The ;tory of 'the discovery has been headlined in every Canadian newspap- er during the last six year., Gilbert LaBilie found veins of pitchblende ore containing roughly $0 nihllgranis of radium to the ton on the snores of Great Bear Lake. six rules from the Arctic •Circle. Though 90 milligrams orf refined radium can be sealed in a tube smaller than amatch, this was considered by scientists as radium - bearing ore of almost incredible rich- ness and naturally ,created world - w ide furore which incidentally echoed thunderously in a number of broker- age house board .rooms. This was the start of Eldorado 'Gold Mines at La - Bine Point in the North West Ter- ritories, But it is doutbtftel if any Canadian mining development ever accumulat- ed, by virtue of its discovery, such an assorted aggregation of stiff 'problems as this one did, To get ore out and supplies or equipment in to the prop- erty there were two alternative meth- ods.

SEAFORTH, ONTARIO. 1,2115-tniMe water route of the Mac kenzie 'River system could be .used, In addition to the handicaps of shal- low draft, tricky navigatine and in- evitatble portages, consideration had to be 'given to the fact that the open season each year was usually six to eight weeks only. 'How both these routes were efficiently developed and how in that chilled and forbidding landscape, a thine and mill, fully elec- trified, were brought to the ,point where, with 100 men at work, produc- tion is now 75 tons a day, are all ro- mantic stories in themselves. The tr-ansportation and application of the explosives required, which is the point at which Canadian industries Limit- ed first enters the picture, would re- quire an entire chapter.

Now and then the performance had all the re- quire 1 e-gttire1 ingredient, of melodrama. \\"lilt the richest ores knower there Iva, no in Canada who lutea' the me- th.,d n+ treating theft. The htirea•tt of \lines at Ottawa plunged into the task of iinding out. Belgian interests, with -•,•.tree; of supply- in the ton ;o, !mid a virtual monopoly on world rad - markets, Ottawa ascertained, it has been publicly stated, that n., help wcnthi be forthcoming trout that gmarter, and it was clear that if Cana- dians were going to win this particu- lar processing battle, they would have to do it unaided, Iu additioo to ore- treating, there ,were other probleme of refining. The extreme rarity of the mineral, the infinitesimal amounts in which it is handled and the very com- plicated nature of the processes would all tend, w•ithi ut any other incentive, to create an atmosphere of mystery around it all. 'Eldorado ,started a .refinery at Port Hope, Ontario, roughly 3,1100 miles away from the mine and amid sur- rou•nditrgs about as different as could well be 'found anywhere in the coun- try. The Bureau of Mines conquered the ore -treating problems. Dr. Marcel Portion, a noted french scientist who began his radium career in the Curie laboratory, came to take charge of the processing and adapted to cotnpera- tirely large-scale .production the me- thods originally worked out by Ma- dame 'Curie. Natnrally, even with the refinery ,in production, the work was largely eaperiinental. The first grant took months to produce. The output gradually increased but it teas not till almost the end of last year that El- dorado officials were ,prepared to say that radium had achieved the status of an indtts'try in Canada and that production was on idi established bas- is, ,At the present time, the capacity of the refinery is being tripled, and this .means that, when complete. Can- ada will be producing radium with an efficiency and in ,quantities never be- fore recorded, Without the chemical industries, no radium could be produced. How com- pletely impossible it would be is ap- parent from the first glimpse inside the reifinery. There is practically no machinery, in the ordinary sense of that word, used for radium concentra- tion. The nearest thing to it is a filter, What the visitor sees is an elaborate and :painstaking chemical perform= ance. The fact that six tons of chem- icals are required to treat one ton of concentrates indicates how elaborate it is and also explains why the refin- ery is located dlose to sources of che- micals and thousands of miles from the mine. Eldorado's slb-arctic veine produce silver -radium ores which are separat- ed and concentrated on the property. The silver concentrates go direct to a smelter. The pitchblende concen- trates are shipped its neat, small bags, —miniature blackish hoops vaguely similar to anthracite but lacking coal's .hard lustre. The ore is so valu- able that the bags in which it is ship- ped from the north are also process- ed, burned and treated as radiutn- bearng ashes. The ore lumps, mark- ed by a cu4•tous concoidal fracture manganese, lead, silica, some sulphur and about about enough non-metallic material, as a rule, to hold the high - ,grades nicely together. ,After roasting to rid the ,combination of sulphur, the demi resulting dust is re -roasted, alter mixing with common salt, to sittapli- fy separation of the remaining sliver. ' The next one hundred steps or so are .very involved indeed, consisting largely of as strenuous and complicat- ed a series of chemical reactions as can be imagined. The dbtiective is .gradually to separate the wantted ele- ments front the undesirables and each other, Shen finally to concentrate the infinitesimally small amount of rad- ium which is to be found in even. the most concentrated ore. • Broadly, the uranium. silver and radium content is the valuable part. The trick is to know which com- pounds of these elements are soluble in acid or alkaline sobutions of .vari- ous types or concentrations and which are not, The solver or silver -lead material i separated as a drab mud, But the ur- anium is ,consistently colorful, and for every pinch of radium salts sufficient to coverta dime, there are tons of ur anium, !I'i'ont the huge vats of dee olive-green uranium liquors to the fin- al bins of powdered sodium -uranium compounds or the red-hot pots of black uranium oxide in the electric furnace. this processing is a matter of striking colour combinations, The so - (limn -uranium powders conte in the bright yellow and orange shades cern in the better autunut leaves. The tank -house, on a zero day, with the su.anting fog from the vats and the meandering t dila ttf hone for sy- phoning, looks like a erose between a. gigantic Turkish h bath and the snake - in a strange rust Tray. of latae p e!listr tint clay -like. blobs of adnur come .franc the tilter< tthiele• a?ter It•tn. e . c a ground in gleaming white puree tin hall mill.. As might be ex- pected, the rotmnercial ti tie of uran- ium salt,, widely used in the ceramic industry, is due chiefly t„ their value its pigments. Lenton -colored crystals of uranium nitrate are also produced, partly rine to the demand for them as chemical curiosities. They are duor- esrent tinder ultra -violet Baht By contrast, actual radio to relining is touch le:, picturesque ;teed utttclt none laborious, though. as it flintier tO popular interest, it is rightly a rout - emit. undertaking. Understanding, of it in improved, incidentally. by know- itt what an isotope is. For a long 'time. scientists believed that no mat- ter where an eleutent,--lead, for in- stance,—might be found, it would al- ways have the sante physical and chemical properties. As it turns out, chemical properties do seem to be the same but one important physical .pro- perty may differ. A cubic foot of lead from one source may not weigh the sante as a cubic foot of lead front an- other. The word "isotope" is used to describe this difference. These different isotopes of elements are quite constant in their weights and at most there are only two or three of thetit for each e+lrntent. Since one of the decomposition products of radium is lead, the lead in this ore, when it occurs, is of special scientific interest. To separate all:tl purify a fewmil- ligrams of radium is a laborious job. 1'o produce several grams a month, as Port FIope is now doing, means a cnntpartivele- enormous output. The processes take many days at best and the refinery practice is to complete a radium batch monthly. It ,is. of course, ntatttlfactltrittg on tt -laboratory scale and the progress can be judged by the size of the weasel used at any •particular point. Rt the start, there are tier, of earthenware crocks, work- ing down gradually through smaller numbers of smaller vessels to a row of monel pails, Two open -pan evapor- ators of glazed earthenware are fol- lowed by sharp -snouted quartz dishes attd .glass flasks, The vessels grow entailer end fewer until, at last. a handful of crystals in the bottom of a beaker represent, weeks of work and tons of the original ore. Fittally. the radium is all processed int single tiny dish of pure silica, one inch and a granter high and one inch and a quar- ter across, heate•I on a single small hot plate in a glass -fronted cabinet, As it arrives it) the radium labora- tory. the radium material, acidified with hydrdlm•,mic arid. is a bubbling chocolate= -coloured batter, But a new and vitally important chemical. not present in the original are, ha.t been added en route. Radium behaves chrntirall vet's smelt like barium. In the earlier separation steps the actual amount ni rarlinut present isfantasti- raltt small by comparison with the other element.. Sin re radium and bar- ium have a natural inclination to stay in each other's company, the chemist add, barium surd has a radihnt=har- iuut combination in sufficient quanti- ty far handling. Wherever the barium goes. tlur chances are the radium will be with it. This added guide really saves the Clay for the chemist and per- mits hint to reach the final stages of refi•n,ing with a radium-rbarinnt mater- ial, He knows that, though be may be sending five thousand barium pol- ice dogs to guard one radium sheep, they will bring the radium home with them, The 'bar.rium, used to round up the medium, must eventull'y be separated from it again and this parting is not to be made quickly, Only very slow- ly .can the barium be coaxed away from the radium. By a tedious sys- tem •of fractional crystallization, the radium .in bromide form is slowly se- parated from its chemical twin, so alike itt a chemical sense but so ab- solutely different in its properties.
