The extraction of copper from sulfide copper concentrate was carried out by using hydrochloric acid and perchloric acid as leaching reagent. In the leaching using only hydrochloric acid except for perchloric acid, the extraction of copper component was low. On the other hand, the addition of ...
Soluble in nitric acid, hot concentrated hydrochloric acid, sulfuric acid and sodium cyanide solution, slightly soluble in ammonium sulfide solution, insoluble in water and sodium sulfide solution. It can be oxidized into colloidal state in humid air. The conductivity is better than cuprous sulfide....

Production of zinc oxide from complex sulfide concentrates using chloride processing hydrochloric acid and oxygen to produce a leach solution; precipitating iron from the leach solution with magnesium oxide; recovering at least one of copper, silver, cadmium, cobalt and lead from the leach solution by...
Dark-blue or black orthogonal crystals; insoluble in water; slightly soluble in hydrochloric acid; decomposed by nitric acid and concentrated sulfuric acid; moderately soluble in ammonium hydroxide; dissolves in potassium cyanide solutions. Uses Copper(I) sulfide is used in luminous paints; antifouling...
Write a balanced chemical reaction for what occurs when copper sulfide reacts with silver nitrate to form copper (II) nitrate and silver sulfide. Is this a redox reaction? Why or why not? A 1.274g sample of copper (II) sulfate was dissolved in water and all...
A hydrometallurigical process featuring treating sulfide metal concentrate with hydrochloric acid or hydrogen chloride gas and an oxygen-bearing gas (air or oxygen) in an aqueous medium to recover metal from said sulfide metal concentrate is disclosed.DUBECK; MICHAEL...
The principal ore of copper is chalcopyrite, a sulfide of copper and iron, also called copper pyrite. Other important ores are chalcocite, or copper glance, a shiny lead-gray copper sulfide; bornite, a lustrous reddish-brown sulfide of copper and iron; cuprite, a red cuprous oxide ore; an...
It is found in two types of ores: (1) sulfide ores, such as covellite,chalcopyrite, bornite, chalcocite, and enargite; and (2) oxidized ores, such as tenorite, malachite, azurite, cuprite, chrysocolla, and brochanite.It is found in most countries of the world, but only a few high-...
A cyclic method of recovering copper, iron and sulfur from iron and copper sulfide bearing materials is described. The method is self-sufficient with regard to iron and copper consumption and gives almost quantitative yields of iron and copper. The method comprises: 1. subjecting a copper bearing...
