Chemistry questions and answers. copper (I) sulfide and oxygen react to form copper (I) oxide and sulfur dioxide: 2Cu2S (s) + 3O2 (g) → 2Cu2O (s) + 2SO2 (g) In the second step, copper (I) oxide and carbon react to form copper and carbon monoxide: Cu2O (s) + C (s) → 2Cu (s) + CO (g) Write the net chemical equation for the production of ...
Sulfide and Oxide of copper in the valence state of II are both a shade of black or very dark blue and are both insoluble in hot water. Considering that there is many more times more oxygen in the air than sulfide, my money goes with oxide. Note that you can smell hydrogen sulfide in the low ppm range. So, if you do not live in Newark, bet on ...
Copper (II) sulfide reacts with oxygen to produce copper (II) oxide plus sulfur dioxide. Suppose you start this reaction with 50.0 grams of copper (II) sulfide and 50.0 grams of oxygen and you actually produce 33.5 grams of copper (II) oxide. Calculate the percent yield for the reaction. 👍. 👎.

ROASTING OF SULFIDE MINERALS In addition to common metals like copper, lead, zinc, and nickel a number of other metals such as antimony, bismuth, cadmium, cobalt, mercury, and molybdenum occur as sulfide minerals. Sulfides are not reduced with the most widely used redu-cing agents, carbon and hydrogen, because the free energy change for the ...
Oxidized copper is a specific type of corrosion that is produced during a three-step process where copper oxidizes to copper oxide, then to cuprous or cupric sulfide, and finally to copper carbonate. It results in a green-colored copper layer or patina that forms over time. Oxidation is one form of metallic corrosion, which is a reaction that ...
Well-developed copper oxide zones appear to form through two distinct mechanisms: (1) via substantial copper addition to a volume being oxidized, including the formation of exotic copper deposits, and (2) through in situ oxidation of a copper-bearing sulfide resource. Importantly, the first type of copper oxide system requires

Copper sulfate is an inorganic compound that combines sulfur with copper. It can kill bacteria, algae, roots, plants, snails, and fungi. The toxicity of copper sulfate depends on the copper content. Copper is an essential mineral. It can be found in the environment, foods, and water.

Oxide–sulfide copper ore was sampled from the ore body Cerovo C1 (south deposit) and used in this study. The chemical composition of the ore sample is pre-sented in Table 1. From Table 1, it can be seen that the high copper concentration is in the sample, as well as the high copper oxide content, while the sulfide copper concentration is lower.
Copper Mining and Extraction: Oxide Ores. Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an ...

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
Preparation and reactions. Cu 2 S can be prepared by heating copper strongly in sulfur vapour or H 2 S. The reaction of copper powder in molten sulfur rapidly produces Cu 2 S, whereas pellets of copper require much higher temperature. Cu 2 S reacts with oxygen to form SO 2:. 2 Cu 2 S + 3 O 2 → 2 Cu 2 O + 2 SO 2. In the production of copper two thirds of the molten copper sulfide is oxidised ...
