How titanium is made material manufacture making

1 At the start of production the manufacturer receives titanium concentrates from mines. While rutile can be used in its natural form ilmenite is processed to remove the iron so that it contains at least 85 titanium dioxide. These materials are put in a fluidized-bed reactor along with chlorine gas and carbon.

Extraction of Iron amp Concentration of Ore An Overview

Sep 23 2019 The extraction of iron from its ore is the third and the penultimate process in metallurgy which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke.

How to Purify Gold Sciencing

Apr 24 2017 The unpurified gold ore is fashioned into a 100-ounce anode whereas pure gold strips make up the cathode. The electrolyte solution is a mix of gold chloride and hydrochloric acid. When an electric current passes from the anode to the cathode through the electrolyte the gold at the anode dissolves and collects at the cathode.
