Extraction of Copper from Copper pyrite - Reference Notes
The principle ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.

EXTRACTION OF COPPER FROM SULPHIDE ORE Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting. Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydro-metallurgical process. EXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of copper.

At higher temperatures up to the melting point of 1,495 °C (2,723 °F), the stable form is face-centred cubic. The metal has 12
Processing of the Pyrite Concentrates to Generate ...
for direct processing to produce sulfuric acid without containing sulfur anhydride and oxygen is achieved by transformation of 60–65% of sulfur of pyrite into SO 2 in the first stage. A number of reactions take place in this process and after this, sulfur anhydride which came with the gas is completely destroyed and the total oxygen of

Mineral Extraction - The Environmental Literacy Council
Mineral Extraction There are two basic types of extraction: surface and sub-surface (deep), each relying on a variety of techniques. Regardless of process, U.S. legislation requires operators to submit a plan for restoring the land and mitigating acid mine drainage before a permit is granted for mining operations.

available for the extraction of gold metal from its ores. Amongst these methods, cyanidation is the most common method used in the leaching of gold from the ore. This process involves the dissolution of gold containing ores in dilute cyanide solution in the presence of lime and oxygen. For refractory ores such as
New Technology of Processing Pyrite Concentrate ...
There are various technologies for processing pyrite concentrates containing non-ferrous metals, Au, Ag, Cu, etc. Often these technologies have disadvantages such as undesired emission of sulfur dioxide into environment, incomplete extraction of useful metals.
So far no account has been taken of the loss of gold which is contained in pyrites, as it has been assumed that these are saved by concentration if they are valuable, and this subject is dealt with in earlier. Nevertheless, as this gold comes under the head of non-amalgamable gold, its physical state and the causes of its disinclination to unite with mercury may conveniently be considered here.
Pyrite should not be present in the base material, subsoil or bedrock under roads, parking lots, or buildings. Oxidation of pyrite can result in damage to pavement, foundations, and floors. In parts of the country where pyrite is commonly found, construction sites …
Pyrite roasting and sulphur burning plants are built for the production of sulphuric acid. Whereas the burning of elemental sulphur is the main source for sulphuric acid, the roasting process is an interesting alternative once pyrite concentrate is available. In addition to these two applications, Figure 1 shows a wider variety of sources for the
