Preparation of Ores - Metallurgist

11/01/2013  In order to increase the iron content of an ore, it undergoes dressing to remove some of the waste component, called tailing. The efficiency of a dressing is assessed either by a concentrate (remaining valuable portion) yield, or by the degree of iron extraction. The concentrate yield is = (O- T)/ (C-T) * 100%

Mineral processing metallurgy Britannica

As a rule, comminution begins by crushing the ore to below a certain size and finishes by grinding it into powder, the ultimate fineness of which depends on the fineness of dissemination of the desired mineral.

Mineral processing - Wikipedia

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
