The Iron Creek Property covers a west-northwest striking, steeply northerly dipping cobalt and copper sulfide
bearing zone named the No Name Zone.
The Bonita property encompasses a district of historic copper, gold and iron workings, unified by a single, district-scale hydrothermal system with a large, mappable alteration footprint covering the entire property, within which copper sulfide
and gold mineralisation has been sampled by VR over an area of about 4 x 5 kilometres.
nanoparticles, whose surface was modified with the organophilic compound of thioglycolic acid, have been used in the polymeric bed in this research.
When the ice melted on Wild-2, the resulting warm water dissolved minerals that were present at the time and precipitated the iron and copper sulfide
minerals we observed in our study," says Lauretta.
The x-ray powder diffraction results unambiguously identified this substance as a copper sulfide
These ligands are then replaced with clusters of metal chalcogenides, such as copper sulfide
The report states, "The two preliminary studies of corrosion of metal components, taken from homes containing the problem drywall, found copper sulfide
in the initial samples tested, which supports the finding of an association between hydrogen sulfide and the corrosion.
Outotec has developed the Copper Sulfide
Precipitation Process, which in collaboration with Canadian miner Barrick Gold Corp (TSX: ABX), will be applied in the Pueblo Viejo project.
Both copper sulfide
and silver sulfide can form black marks on the skin.
Formation of copper sulfide
layers on the surface of polyethylene films of various density by the use of polythionic acids.
Today the Butte mines are closed and flooded, but its mineralogical legacy of fine specimens remains--most noteably the copper sulfide
and sulfosalt minerals such as bornite, chalcocite, chalcopyrite, colusite, covellite, digenite, djurleite, and enargite, and other minerals such as barite, pyrite, quartz and silver.
Previously, copper sulfide
was being used for the solid electrolyte in NanoBridge(R); however the following issues remained through its use.
