California Mining Journal (PH 16-14)(April 1943) (36 pages)

California Mining Journal, April, 1943 TWENTY-ONE Wa the Grass Valley district has suffered a decided blow from the government’s gold mine closing order, now having only 540 miners at work, as compared »with approximately 2,600 in the boom days, some ray of hope for better days will be forthcoming when the announcement of a magnesium operation for the district is «made. Ft To Use Brandenburg Process About this, time last year California Mining Journal was, as some of our critics say, “ “going off the deep end” in the matter of doing a little boosting for the patented process of extracting magnesium metal from serpentine. Everyone knows how much eer“pentine there is in our mining areas—billions and billions of tons—and when H. R. ‘Brandenburg, then head chemist for the Cowell Lime & Cement Co., Concord, Cal., gave out the information that none of the serpentine of Northern California and Southern Oregon would run less than 300 *. pounds of: magnesium metal to’ the ton, and the light metal was selling for 27 cents per pound, we conceived a brand new industry for the* West. And the Journal then did “some work for Brandenburg and his process. “The upshoot of it was that “Brandy” was “ealled to Grass Valley for a number of con“ferences, the*result being that on Oct. 1st, 1942, ‘the resigned his position with the Cow‘ell company and went to Fresno, Cal., where he carried’ on; tests and operation plans desired by his backers.
