2015-1-1 Shen et al. (2012) also found that acidophilic bioleaching microorganisms effectively bioleach phosphorus from iron ore when they added high-phosphorus iron ore and elemental sulfur to municipal wastewater to make an iron ore slurry. Apatite was the main phosphorus mineral in the iron ore and the wastewater contained native sulfur-oxidizing ...

The aim of this research was to study the rare earth (REE) minerals in ooidal ironstone deposits of the West Siberian basin and the Turgai depression. Authigenic minerals (monazite and cerite) were described, and their main mineral form was identified as light rare earth element phosphate (LREE-phosphate) in this study. LREE-phosphate is included in ferruginous ooids, peloids,

Phosphate mining is an important part of the process of producing chemical fertilizers. The specific processes used to extract phosphate rock depend on the geographic characteristics of the area in which the mineral deposits are located. Most phosphate mining is conducted as open-pit mining rather than subsurface mining.

2021-12-11 The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes

2019-10-9 Blast furnaces extract pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide: 2C(s)+O2(g)→2CO(g) In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g) Write the net chemical equation for
