Sep 10, 1974· This invention relates to the novel use of certain compounds as flotation reagents in producing oxide copper ore concentrates by flotation separation and, in particular, to producing copper concentrates by flotation separation of ores containing copper in oxidized form such as malachite, azurite, cuprite, tenorite and chrysocolla.
leaching was investigated with respect to acid concentration and solid to liquid ratio. The copper concentration in the leach solution ranged from 0.80 to 1.75 g dm-3. The total Cu recovery rate ranged from 30 to 56 %, whereas the recovery rate of copper oxide minerals ranged from 67 to 100 %. Furthermore, with increasing the amount of liquid
This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from : % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of .
The principle ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.
Copper has a great variety of uses including construction, electrical wiring and plumbing. Alloys of copper include tin, which is an alloy of zinc and copper and bronze, which is an alloy of copper.

Full Answer. Copper ores generally contain sulfides or oxides and copper in the 0.5 to 2.0 percent range. Because of the greater value of copper metal, refining ores at these levels is profitable. Refiners crush copper sulfide ores mechanically and use froth floatation to bring copper-containing particles to the surface of a water solution.

Three copper ore with differs concentration using oil as fuel for burningand that 5% of the amount of ore. The gases burning gases concentration join and leave through the flue. Sulphur passes into the furnace of SO 2. Oil for burning contains 85% C and 15% H 2.The chemical reactions that take place during the concentration process ores are: Cu 2S+2O
Concentration A series of flotation tests was run to determine the best grind and reagent combination for treatment of the ore. Although good recoveries of copper were ob- tained by rougher flotation of ore ground to minus-48- or 65-mesh, difficulty was experienced in cleaning the rougher concentrate.
Leaching of copper oxide with different acid solutions. It was found that 99.95% of copper was dissolved after 14min with inorganic acids at 0.5M, 25°C and l/s=10ml/g while more drastic operation conditions were needed to reach the same dissolution efficiency with citric acid solution. Anions seem to be involved in the surface reaction.
Pre-concentration of copper ores by high voltage pulses. Part 1: Principle and major findings. Abstract A novel ore pre-concentration technique using high voltage pulses is proposed in this study.

decomposes during concentration so that any part of the ore to be in contact with air O 2.For this work at all times, the furnace for concentration should be done ore blending. The quantity of air that inflates and his preheating represents one of the most important factors of the process of copper ore in furnaces for concentration concentration.
a) ores contain a large concentration of a particular mineral; a rock may or may not be an ore b) ores contain only metallic minerals; rocks contain only nonmetallic minerals c) ores are always profitable to extract; rocks are never profitable to extract
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 ...
The Copper Mining Process. During the Industrial Revolution, coal- and steam-powered machinery paved the way for a huge increase in copper production with mines smelting between 200 and 300 tons of copper ore per week. At the beginning of the 20th century, the annual worldwide copper demand was at half a million tons.
A little more than 100,000 gallons of water per ton of copper was used in the production of copper from domestic ores. Of this amount about 70,000 gallons per ton was used in mining and concentrating the ore, and about 30,000 gallons per ton was used to reduce the concentrate to refined copper.
