the chemithe separation methods used to mine copper
Copper extraction
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper ores consists of a series of physical, chemical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores.

A Review of Nickel, Copper, and Cobalt Recovery by Chelating Ion
Copper and cobalt can be found on nickel laterite ores, and cobalt can be found also on copper ores, and many contaminants such as iron, aluminum, and magnesium are associated with these ores. In hydrometallurgical process, a purification step is necessary after leaching due to the presence of these impurities. Chelating resins are Copper and silver were extracted both from mineral residues and fresh mineral tailings by mixing 0.5 g of representative samples with 10 mL of a solution containing 3.42 M NaCl and 0.2 M HCl ( Romero et al., 2003 ), and heating for 1 h at 90 °C. 2.4.

Study on the Methods of Separation and Detection of Chelates
Liu & Dongyun Yan (2019): Study on the Methods of Separation and Detection of Chelates, Critical Reviews in Analytical Chemistry, DOI: 10.1080/10408347.2019.1573657 To link to this article: httpsIf copper and cobalt-containing ores are processed, solvent extraction is the most effective method for separation. In this case, since copper is the main mineral, the aim is to eliminate the cobalt present from the circuit, which ends up in refining together with the rest of the impurities. The process itself is quite similar to copper miningCobalt Extraction Mechanisms SpringerLink

Copper Recovery and Reduction of Environmental Loading from Mine
The flotation tailings obtained from Bor Copper Mine contain pyrite (FeS2) and chalcopyrite (CuFeS2), these sulfide minerals are known to promote acid mine drainage (AMD) which poses a serious threat to the environment and human health. This study focuses on the treatment of mine tailings to convert the AMD supporting minerals to The use of sulfuric acid in an acid leaching process is a conventional method for recovery of copper, but in some cases it is necessary to use other reactants such as ammonia. Ammonia has been known as an effective leaching agent in hydrometallurgical procedures, although it has been less studied than the chemical Ammonia Leaching: A New Approach of Copper Industry in

Metals extraction processes from electronic waste: constraints and
They used leaching (80 °C, 3 h) process in acidic atmosphere (H 2 SO 4) and followed by electrodeposition method for copper recovery. 99.5% pure copper was recovered with 97% recovery efficiency. Electrodeposition method is highly selective, ecofriendly (no secondary pollution), efficient metal recovery method comparing to the 1.3 Run-Of-Mine Material and Minerals. Generally, mineral processing begins when an ore is delivered from a mine, to a processing facility. At this point, the ore is called run-of-mine material because there has been no treatment performed on it. There are three primary types of run-of-mine materials: Run-of-mine consisting of useful materials.Introduction to Mineral Processing or Beneficiation Sepro Labs

Chemical Composition Data of the Main Stages of Copper MDPI
The mining industry has faced significant challenges to maintaining copper production technically, economically, and environmentally viable. Some of the major limitations that must be overcome in the coming years are the copper ore grade decline due to its intense exploitation, the increasing requirements for environmental protection, and Copper slag is generated when copper and nickel ores are recovered from their parent ores using a pyrometallurgical process, and these ores usually contain other elements which include iron, cobalt, silica, and alumina. Slag is a major problem in the metallurgical industries as it is dumped into heaps which have accumulated into millions Environmental and Socioeconomic Impact of Copper Slag—A
