Toxic chemicals are used in the Flotation Process to separate the copper and molybdenum out of the milled powder This Flotation process is the major extraction method at Duval/Sierrita mine because of the poor quality of the copper at this site Some chemicals produce bubbles that that the copper adheres to and the "bad stuff" falls to the bottom....
THE Navy's report Man-Made Vitreous Fibers, discusses three principal classes of manufactured vitreous fibers (MVF): fibrous glass, mineral wool (slag and rock wool), and refractory ceramic fibers The manufacturing processes and chemical composition of each fiber class varies depending on their specific end use; however, categorizing fibers into these classes does not capture the diversity of ....

Some of us who have been acquainted with the present methods of production of metals, and who have had an opportunity to witness the impact of some of the newer chemical techniques on metallurgy, have become convinced that it is possible to consider seriously the treatment of sulfide minerals by strictly chemical methods as distinct from pyrometallurgical methods...
The mining process involves the excavation of large amounts of waste rock to remove the desired mineral ore The ore is then crushed into finely ground tailings for chemical processing and separation to extract the target minerals...
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy...
Another method of concentration of ores is the Froth Flotation Method This is the process for concentration of primarily sulphide or It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals The process uses the difference in the wetting characteristics of minerals and gangue ....
