Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.

Direct cyanidation of Ore A yielded poor gold extractions in the mid twenty percentile for ore ground to a P 80 of 53 micrometres. Some test work investigated cyanidation of tails but the grade of the gold in the tails was significantly low to be of value (0.2 g/t). Average cyanide consumption was 2 kg/t.
Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper .
Only then are the copper minerals broken free of the rest of the rock to be separated by flotation. Concentrating The slurry of water and pulverized ore is mixed with milk of lime to raise the pH and small amounts of special reagents: a frother to make bubbles, and a collector chemical that causes the copper minerals to stick to those bubbles.
The underflow gangue (waste) from the rougher and scavenger cells flows to a tailings thickener to recover water for the process. Filters dewater these tails further, or a tailings pond stores them. Bulk (Copper-Moly) Thickener. A high-rate thickener dewaters the bulk of copper-moly concentrate before more separation. Moly Flotation
The Miami Copper Company's· property has been an underground 'minirig operation with a block-caving system of mining to take out the ore. When the 6,000 ton mill was ready to start in 1911, gravity concentration was standard practice, and the mill was equipped with chilean mills for fine-crushing, and tables for concentration.

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
also use diesel fuel for surface hauling of ore to the mill. Approximately 155 pounds of explosives are used for every short ton of copper produced in underground mines.s The average grade of the ore mined, the ratio of overlying dirt and rock (overburden) to the ore body (stripping ratio), and the depth of the pit 5Gaines, supra note 3.
