Extraction of Metals Methods of Extraction of Metals
Isolation of elements in Chemistry class 12 aims to teach the students about various processes of extraction of metals from ores. Very few metals such as the noble metals, i.e., Gold, Silver, and Platinum etc. are present in their original metallic forms in nature. Metallurgy is the field of science which deals with the extraction of metals from ores which are naturally found in the environment.Онлайн-запрос

CLASS XII CHEMISTRY Metallurgy
The extraction and isolation of metals from ores involve the following major steps: • Concentration of the ore, • converting ore into oxide • Reduction • Refining (Purification of the metal.)

Extraction Of Copper | Mining, Concentration, Smelting
Collectors (pine oils, fatty acids etc) increase the non-wettability of the metal part of the ore and allow it to form froth and Froth Stabilizers (cresols, aniline etc) sustain the froth. The oil wets the metal and the water wets the gangue. Paddles and air constantly stir up the suspension to create the froth. This frothy metal is skimmed off the top and dried to recover the metal.Онлайн-запрос
