How Is Platinum Extracted? - Reference.com

Apr 13, 2020· Platinum is an incredibly rare metal that is mined and extracted in a variety of different ways depending on the technological sophistication of the miners attempting to extract it. It is incredibly difficult to find in large pure quantities, so it needs to be extracted from the ore in a very specific way.

Titanium processing - Extraction and refining | Britannica

Titanium processing - Titanium processing - Extraction and refining: The production of titanium metal accounts for only 5 percent of annual titanium mineral consumption; the rest goes to the titanium pigment industry. Pigments are produced using either a sulfate process or a more environmentally acceptable carbo-chlorination process (described below) that converts TiO2 into TiCl4.

The Properties and Applications of Platinum

Aug 21, 2020· The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'. During flotation, air is pumped through the ore-water slurry. Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining.

(i) What is the principle behind the zone refining of ...

(i) The technique of zone refining is based on the principle that the impurities are more soluble in the molten state of metal than in the solid state. Silicon, boron gallium, indium etc. can purify by this process. (ii) Ores of copper contain iron oxide as an impurity. Silica reacts with iron oxide and forms iron silicate, which is removed as slag.
