At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite CuFeS 2.From the formula, it is clear that iron and sulphur have to be removed in order to produce copper.

Copper Sulphuric Acid

Outokumpu flash smelting is a closed process which can achieve up to 99% capture of the sulphur-rich gases from the smelting furnace for the production of sulphuric acid. The technology was first introduced at Outokumpu's Harjavalta smelter in Finland in the late 1940's.

Copper processing Roasting, smelting, and converting

Copper processing Copper processing Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined

chemical reaction Definition, Equations, Examples

Chemical reactions are an integral part of technology, of culture, and indeed of life itself.Burning fuels, smelting iron, making glass and pottery, brewing beer, and making wine and cheese are among many examples of activities incorporating chemical reactions that have been known and used for thousands of years. Chemical reactions abound in the geology of Earth, in the

HYDROCOPPER A NEW METHOD FOR TREATING COPPER

Outokumpu has developed a new chloride leach process, called HydroCopper®, to treat copper concentrates. Chalcopyrite is quite refractory in leaching and in sulfate milieu an autoclave of high temperature and pressure is required. However, in the HydroCopper®-process copper sulfides can effectively be leached in atmospheric pressure using strong,

Copper Reactivity Etching: a KS5 chemistry resource on

The Chemistry of Copper Etching. The process has three reactions: Equation 1 FeCl 3 + Cu → FeCl 2 + CuCl. Equation 1 will do the etching by itself because the metallic copper atom has been oxidised and becomes a copper ion within the copper chloride in solution, but a second reaction happens, making this a two-step redox reaction.
