As one example, basic copper carbonate was wet ground with elemental sulfur and appropriate additives such as ammonium sulfate to transform the surface chemical composition from oxide to sulfide.

The Sulfur Problem in the Metallurgical Industry

2019-11-17  In the copper industry high-grade massive sulfide ores were broken down into small lumps and charged to a vertical furnace whereby the unwanted rock was removed as a slag and the copper-containing minerals were collected as a matte. Sulfur dioxide was emitted in this process and no attempt was made to capture it.

1981-3-4  The copper-sulfur system itself is very complex, and has been well defined only in the last 15 years. The phase diagram was first adequately mapped out by Roseboom (1966). The system has since been thoroughly restudied by Cook (1972) and by Potter (1977), both

Cutting Fluids for Machining Thomasnet

2021-5-10  Copper Alloys: Most brasses, bronzes, and copper are stained when exposed to cutting oils containing active sulfur and chlorine; thus, sulfurized and sulfochlorinated oils should not be used. For most operations a straight soluble oil, mixed to 1 part oil and 20 to 25 parts water is satisfactory. Grinding: Soluble oil emulsions or emulsions

Molecules pressured to react Nature
