The Effect of Oxidation on the Flotation Behaviour of Nickel-CopperOres S Kelebek 1 ABSTRACT Surface oxidation is one of the most imponant factors that influence the flotation selectivity and recovery in the processing of complex sulphide ores. It is an inherent part of … Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

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. Most of the copper ores mined in the United States contain only about 1.2-1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2 , also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an oxide ore.

Operations at Miami 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, The large pieces of ore are collected by haul trucks and taken to a mill, a large rotating device which makes the pieces smaller through crushing and grinding. There are two types of copper ore (sulphide ore and oxide ore), and each is treated differently in order to liberate the copper inside. Step 3. Sulphide ore – treatment process

Sulfide-Ore Copper Mining or (not and) a Sustainable Boundary Waters Economy ii In a world where many jobs can be done from almost anywhere, economic research must begin with an understanding of what it is that makes people choose any given location. This is not to say that the  · 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

Many of our largest copper deposits contain both sulfide and oxidized copper minerals. The large porphyry mines, with a total copper content of from 1.3 to 2.0 per cent., send to their mills ore with an oxide content of from 0.2 to 0.4 per cent. Sulphide ores are the major source of valuable metals such as copper, lead, zinc, and nickel, as well as gold, silver, and platinum group metals (PGMs), and flotation is the dominant industrial process to recover these metals via the production of a sulphide concentrate.

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water ... In many locations where they had initially been recovering 90% of the assay values processing oxidized surface ore, with the rebellious sulfide ores they were recovering less than 50%. The rest of the precious metals in their ore simply flowed uselessly out from the mill and into the tailings pond.
