Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.This …
These bacteria obtain energy by oxidizing ferrous iron (Fe 2+) to ferric iron (Fe 3+) or elemental sulphur (S 0) or other reduced sulphur compounds to sulphuric acid (H 2 SO 4). The released Fe 3+ and hydrogen ions then break down the sulphide matrix . This is summarized in the equations below using pyrite as a typical example of gold bearing ores:

Iron beneficiation has been evident since as early as 800 BC in China with the use of bloomery. A bloomery is the original form of smelting and allowed people to make fires hot enough to melt oxides into a liquid that separates from the iron. Although the bloomery was promptly phased out by the invention of the blast furnace, it was still heavily relied on in Africa and Europe until the early part of the second millennium. The blast furnace was the next step in smelting iron which pr…
