The roasted product, calcine, serves as a dried and heated charge for the smelting furnace. Smelting of roasted (calcine feed) or unroasted (green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide (FeS), and some heavy metals. Converting the matte yields a high-grade "blister" copper, with 98.5 to

Solubility product constant ( Ksp) (or the solubility product) is the product of the molar concentrations of the constituent ions, each raised to the power of its stoichiometric coefficient in the equilibrium equation. For instance, if a compound A a B b is in equilibrium with its solution. A a B b (s) → a A + + b B.

Applied across the industry, improved coarse particle flotation can result in an additional 0.5 million to 1.5 million metric tons of annual copper production by 2032. If applied across all metals found in sulfide deposits, the technology represents potential value creation of $9 billion to $26 billion per year.

The nucleation rate of the copper sulfide product was reduced in the initial stages of sulfurization after (NH 4) 2 SO 4 was added. Thus, covellite (syn, CuS) with larger crystal grains was formed on the azurite surface, as confirmed by X-ray diffraction. Ultimately, more copper sulfide products were formed on the azurite surface, …
