Beneficiation of titaniferrous iron ore sample - CORE

A few sporadic deposits of titaniferrous iron ore are located in Gondia area of Maharashtra. In this area, the ore occurs in the form of lumps as well as fines in the ratio of 1:1 and mostly comprised of iron bearing mineral of hematite followed by magnetite and ilmenite. Both the iron oxide minerals are titaniferrous containing 11.25% TiO2.

Processing, smelting and refining gold | World Gold Council

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
