This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Mining and Extraction . Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide mineral ore. Having a quick look now at how porphyry ores are treated and the metals extracted. There are two main ...read more
is recovered by means of a pollution-free hydrometallurgical which entails leaching and converting the with sulfate in order to produce an insoluble sulfide, a soluble iron sulfate and sulfuric acid. A secondary leach is then conducted in order to react the sulfide with oxygen in the presence of a jarosite-forming cation to ...read more
· In the present study, Cu and iron boride FexB were produced for the first time through molten salt electrolysis using CuFeS2 in an oxide-based borax electrolyte. Molten salt electrolysis was carried out at 1073 K and a current density of 600 mA/cm2 for 3600 s under galvanostatic conditions. Cu and Fe/FexB were deposited on the graphite crucible surface as the ...read more
- From Beginning to End. is a major metal and an essential element by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and about 10,000 years ago. And as alloyed in bronze -tin alloy about 3000 BC, was the first engineering known to man.read more
A gaseous chlorination for hydrometallurgical treatment of a concentrate was investigated. The overall is visualized to consist of low temperature chlorination-selective oxidation, followed · by aqueous chloride leaching and SX-EW for producing electrolytic , elemental sulfur and ferric oxide.read more
· The II ion in the is reduced to I sulfide which is reduced further to in the final stages. The iron in the ends up converted into an II silicate slag which is removed.read more
· Extracting from its ores. The method to extract from its ores depends on the nature of the ore. Sulfide ores such as CuFeS_2 are converted to by a different method from silicate, carbonate or sulfate ores. also known as pyrites and similar sulfide ores are the commonest ores of ...read more
· The ore is pulverized in a hammer mill, run through a flotation to separate the useful mineral from the dross, then roasted to produce oxide, reduced with carbon, and finally purified electrolytically. The crud that drops to the bottom of the electrolysis tank often contains useful amounts of other , such as gold or silver.read more
· In 1546, Georg Agricola named this brass shiny mineral Kupferkies gravel.The name , which is now common in mineralogy, Greek chalkos = , pyros = fire was introduced by Henckel in 1725. The mineral has a tetragonal crystal structure at the space group I42d and the composition CuFeS 2.The structure can be derived from the sphalerite α-ZnS, by doubling …read more
6 An ore of is the mineral, . This is a mixed sulphide of iron and . a Analysis of a sample of this ore shows that 13.80 g of the ore contained 4.80 g of , 4.20 g of iron and the rest sulphur. Complete the table and calculate the empirical formula of . …read more
