  • Copper Ore an overview ScienceDirect Topics

    The principal copper ore mineral is chalcopyrite (CuFeS2), which is commonly smelted to yield a matte containing ∼50% copper. In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the Cu–Fe–S–O system at 1 atm SO 2 as a function of temperature (Rosenqvist 1978).Copper Mining and Extraction Sulfide Ores,The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other

  • Copper processing Ores Britannica

    The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper. weight percent of copper in ores USU,2014-10-29 · Copper is reduced at potentials more positive than the reduction of hydrogen ion, so it can readily be deposited on a platinum cathode from acidic solutions. A schematic of the electrolysis apparatus used in this experiment is shown below. In this experiment, the copper ore sample is first oxidized to dissolve all the analyte.

  • BotEC: Percentage of Copper in Ore

    2021-5-30 · The copper ore forms only 0.7% of the rock. We need to find a number that we can multiply by .007 to get 90 kg. Dividing 90 kg by .007 will give us that number—approximately 12,860 kg. Multiplying that number by 2.2 pounds/kg would give us the number of pounds (about 28,300 pounds).Silica is added to roasted copper ore during extraction ,Silica is added during smelting in order to remove iron oxides from copper sulphide and oxides. During roasting the iron sulfides react with oxygen (in air or oxygen enriched air) to produce iron oxides (mainly as F eO, but with some magnetite (F e3. )) and sulfur dioxide.
