Ore processing – Waihi Gold

Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along .

Extraction and Recovery of Cerium from Rare Earth Ore by .

Rare earth elements are widely found in many minerals, some of which, such as bastnaesite, monazite, and xenotime, are of great commercial value. Cerium (Ce) is the rare earth element with the highest content in light rare earth ore. Solvent extraction is the most effective and efficient method to recover and separate Ce from other light rare earth elements.

Chloride process - Wikipedia

The chloride process is used to separate titanium from its ores. In this process, the feedstock is treated at 1000 °C with carbon and chlorine gas, giving titanium tetrachloride.Typical is the conversion starting from the ore ilmenite:. 2 FeTiO 3 + 7 Cl 2 + 6 C → 2 TiCl 4 + 2 FeCl 3 + 6 CO. The process is a variant of a carbothermic reaction, which exploits the reducing power of carbon.
