Show metallurgical SUCCESSES it can truly be said that one of the most important factors entering into mining operations on a large and diversified scale at the present time and the s satisfactory at is factory resu results lis hp be ing chronicled can be designated de signa ted as the metallurgical triumphs of this aa day Y and abid age and the bringing of ore redaction tion ineth and processes up to an exact science years ago ago M but few ways of extracting mo m callic values from ores were known to the mining world the stamp mill was the favorite in the handlin handling t cr of free milling gold and silver ores and with fire a certain class of rebellious ores could be successfully treated at this point the miner and millman encountered breakers breatt ers ahead and while many propositions of merit and value value appealed to them strongly they were compelled to ignore mining propositions which today are being operated at a handsome 1 profit because of the invention and discovery of methods for ore treatment which were not even dreamed of twenty five years ago for instance the concentrating table is of quite recent origin and by its use low grade sulphide ores can be handled at a pro profit fit which were practically valueless several years ago low grade oxide gold ores ten years year s ago were worthless until the discovery and utilization of the cyanide processes and now base ores of low value can be successfully milad ed by the cyanide process after first being 0 roasted low grade copper ores are ano alio being treated successfully at the present time that would not have been looked at by the mining operator and millman fifteen years ago acro and this because of the fact that the smelter or roaster has become an im important factor in pre preparing paring ores of this character for the smelter stack and refinery refine ry lin jin addition to which several copper leaching processes have been invented by the use loi which low grade copper ores can be worked w to advantage and at a profit then we have hav ie new methods for the recovery of values from tailings and slimes and in placer mining ap operations arati erat ions ons the inventive genius has perfected various appliances so that the fine and flour gold can be arrested and diverted to the copper plate or amalgam pot the successes attending the research and untiring efforts of the m millman the metallurgist and chemist in the endeavor to perfect methods for the successful recovery of the precious metals and their products byproducts by have been attended by such magnificent triumphs that in these days no mining project need be rejected because of the belief that this or that class of ore or ores can not be successfully worked show the metallurgist your ore and he will show you a process for its reduction to this fact can be attributed the unqualified success which has attended mining operations during the past few years and this condition is largely responsible for the widespread inter est now being taken in mining operations io the world over |
