Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs. Also, considerable attention is paid to automatic sensing devices and automatic controls in order to …
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 several countries around the world, abandoned mining sites are blighted by pollution from metal and metalloids. Generated by mining processes, toxic pollutants have lasting effects on the ecosystem. The study examined the environmental impact of waste from a copper mine that was operated by the Caucasus Copper Limited Company between 1905 and 1928, …
The above is the application of flotation process and beneficiation equipment of copper-nickel sulfide ore. In the actual beneficiation plant, the beneficiation test should be carried out first, and the nickel ore beneficiation method should be scientifically and rationally designed according to the test results to obtain the ideal beneficiation plant benefit.

The flowsheet discussed in this study is for treatment of 100 tons per day oxide-sulfide copper ore by the leaching process using sulfuric acid-ferric sulfate solvent. This flowsheet would also be suitable for a larger tonnage by proper sizing of the various units of equipment.
The sulfide ore is then roasted or smelted into a purer copper concentrate called a slab. Finally, the copper slab undergoes electrolysis, resulting in 99.99% pure copper cathode slabs. ... Additionally, modern mining equipment reduces waste and decreases chemical exposure during all phases of the copper mining process.
For lower-grade deposits located near the surface, the open-pit method is the most practical for the mining of large tonnages of material. Large track-mounted drills prepare the ore for blasting, and the broken ore is hauled to the ore-dressing plant by truck (at up to 150 tons per load) or conveyor. In underground mining, vertical shafts are sunk well over 1,000 metres (3,300 feet) …
