· Copper sulfate (CuSO4) provides a source of copper ions. Sulfuric acid (H2SO4) makes the bath conductive and acts as a charge carrier. Chloride ions (Cl) combine with the organic species to form a complex that slows down plating rate on selective areas.
6. Refining Copper from the smelter is melted and cast as anodes, the solution from the solvent extraction process moves to a plating operation. 7. Sulfide Ore Refining The final step in processing sulfide ore copper from the smelter is to make high purity copper hodes. 8. Copper Products Many Uses
About 80 % of primary copper production comes from lowgrade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate
This work focused on purifying copper electrolytes from a bismuth impurity on a laboratory scale. The electrolyte came from Polish copper electrorefineries with the content of main components, g/dm3: Cu, 160 H2SO4. The electrolyte was enriched in bismuth by Bi2O3 addition. Purifiion of bismuth contamination was carried out using selected agents with adsorbing .
of PE was explored. The objective was to provide a basis for preparation of PE for food industry appliion. 2 Materials and methods Preparation of CuONHAP A g Cu(NO 3 2 ·3H 2 O was taken to prepare the Cu(NO 3 2 solution with 5% Cu mass fraction. A 2 g of nano hydroxyapatite (NHAP) after reaming treatment was added to the solution.

Pure oxygen filtration. Nitrogen and hydrogen (no sulfur) filtration. Sand removal and purifiion of crude oil. Made as sintered muffler silencer. It can be used as sensor metal filter. Features of sintered copper powder filter elements: Large dirt holding capacity. High precision and high porosity. Good air permeability and small pressure loss.
Copper metal is extracted from molten matte through bessemerization. The matte is introduced in to Bessemer converter which uphold by tuyeres. The air is blown through the molten matte. Blast of air converts Cu 2 S partly into Cu 2 O which reacts with remaining Cu 2 S to give molten copper. 2Cu 2 S + 3O 2 2Cu 2 O + 2SO 2 2Cu 2 O + Cu 2 S 6Cu + SO 2 The copper so .
