Copper Mining and Extraction: Oxide Ores

Leaching Oxide Ores with Sulfuric Acid. Copper is stripped from the steel cathode plates when it is thick enough. This cathode copper is 99.99% pure. Solvent Extraction and Electrowinning (SX-EW) production, virtually non-existent before the 1960s, reached nearly 3.8 million tonnes of copper in 2013.

Oxide Copper Leach Modeling

A modified steady-state approximation of the continuity equation has been applied by Madsen and Wadsworth to the leaching of enriched copper sulfide ores. The modeling of the leaching of copper oxide ores has not received as much attention as sulfide heap leaching. The acid leaching of copper oxide ores generates a vertical acid concentration gradient in the ore heap, which is not generally …

Copper Mining and Processing: Processing of Copper Ores ...

This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leaching is the process of using percolating stone solutions to leach out metals. Heap leaching is very commonly used for low-grade ore, which would otherwise not be …

Copper Leaching Method - Metallurgist & Mineral Processing ...

Copper Leaching Practices. For centuries small amounts of copper have been recovered from acid mine-drainage waters. In recent years, the expansion of copper-bearing waste dump leaching for copper recovery has established a technological basis that is rapidly converting the art of copper leaching into a science.

Leaching of copper oxide with different acid solutions ...

Oct 15, 2009 · Leaching experiments were carried out in a water bath with 0.5 M acid concentration at temperatures ranging from 40 to 80 °C in steps of 20 °C and with agitation speed of 400 rpm. At temperature lower than 40 °C and l/ s < 40 ml/g, no dissolution of copper was observed. As can be …

Heap leaching - Wikipedia

Nickel ores. The method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores (as high as 1,000 kg of acid …

Copper extraction - Wikipedia

Smelting. Copper can be lost from the matte in three ways: as cuprous oxide (Cu 2 O) dissolved in the slag, as sulfide copper dissolved in the slag or as tiny droplets (or prills) of matte suspended in the slag. The amount of copper lost as oxide copper increases as the oxygen potential of the slag increases.

Copper recovery using leach/solvent extraction ...

Copper recoveries of 85% are being reported at several oxide heap operations and many chalcocite heap leaches report 75% to 80% copper recovery. Sulphuric acid leach solutions treated successfully by copper SX range from <1 g/ lCu up to about 35 g/ Cu with a pH range of ~0.8 to ~2.5.

Recovery of Copper from Reverberatory Copper Slag and ...

Figure 1. Schematic flow diagram for leaching of copper slag. The mineral composition is given in Table II. The major phases are fayalite with silicates. The amorphous content of the copper slags is high, approximately 30%. The slag is a complex mixture of metals, sulphides, silicates and oxides with a glassy amorphous material.

Chapter 6 Copper Production Technology

Zqsolution mining is the leaching of ore with water-based chemi- cal solutions. In situ solution mining treats the ore in place;I.e., without miningIt first. open pit mining offers the highest production rates and leaves the least ore behind. However, underground mining can reach greater depths.
