The pad is lined with synthetic or natural materials such as polyethylene or compacted clay. Copper heap leach operations are much smaller than copper dump leaches.

Copper Ore Leaching Process-Series II

Jun 07, 2016· With organic amine as collectors, amine flotation technology of copper leaching is suitable for copper ore like malachite and azurite. In copper leaching plant, the main amine collectors are cocoanut oil amine and lauryl amine; the relatively effective inhibitors include sodium alginate, lingosulfonate, polyacrylic acid and fiber lignin sulfonate.AN INTRODUCTION TO COPPER EXTRACTIONDue to the vast quantities of copper ore and the relative inefficiency of the Stage 1 plant, a Stage 2 upgrade has been initiated. The Stage 2 upgrade is expected to increase copper output to secondary crushing facility in the form of a Ball Mill, numerous leaching and thickening tanks, a tailings disposal facility, and a Solvent ExtractionGlossary of Mining TermsHead grade - The average grade of ore fed into a mill. Heap leaching - A process whereby valuable metals, usually gold and silver, are leached from a heap, or pad, of crushed ore by leaching solutions percolating down through the heap and collected from a sloping, impermeable liner below the pad.Gold cyanidationGold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver representsprocess flow of copper millingThe copper ore usually contains a large amount of dirt, clay, and a variety of noncopper bearing minerals. The first step is to remove some of this waste material. This process is called concentrating and is usually done by the flotation method. 3 The ore is crushed in a series of cone crushers.

SOUTH AMERICA

FCX's South America mining operations include open-pit mining, sulfide ore concentrating, leaching and solution extraction/electrowinning. Production from these mines is sold as concentrate or cathode under long-term contracts. Our South America mines also ship a portion of their copper concentrate to Atlantic Copper, our wholly owned smelting and refining unit in Spain.Leaching of Primary Copper Sulfide Ore in Chloride-FerrousCopper extraction from primary copper sulfide ore from a typical porphyry copper deposit from Antofagasta, Chile, was investigated after leaching with a chloride-ferrous media at two temperatures. The study focused on whether this chemical leaching system could be applied at an industrial scale.
