1. Crushing and grinding: The first process in metallurgy is crushing of ores into a fine powder in a crusher or ball mill. This process is known as pulverization. 2. The concentration of ores: The process of removing impurities from ore is known as a concentration of minerals or ore dressing. In metallurgy, we concentrate the ores mainly by ...


29.2 | Extractive Metallurgy 2. TYPES OF ORES Ores may be classified mainly into following 4 classes:- (a) Native ores: They contain the metal in a free state, and are found in the association of rock or alluvial impurities like clay, sand etc. Silver, gold, platinum etc. occur as native ores. Sometimes, lumps of almost pure metals are also found.


2. Chemical reduction, or smelting, is a form of extractive metallurgy. 3. To convert an oxide of iron to metallic iron it must be smelted or sent through a direct reduction process. The main use of smelting is to produce a metal from its ore.This includes iron extraction (for the production of …


The first objective of Mineral Processing and Extractive Metallurgy is to remove the Mineral as soon as freed and as coarse as possible" is the first rule in treating complex ores. Ores containing two or three metals have been satisfactorily treated for a number of years. Today, however, ores containing as high as four, five and even six and seven minerals are being efficiently concentrated.

Metallurgy is a subject evolved over a few millennia, at least the past 3000 years, probably since the dawn of known human history. Old Greek, Hebrew and Hindu scriptures allude to metals like gold, silver, copper, iron, lead, and tin as well as nonmetals like sulfur and carbon [1].Ancient Greek philosopher Heraclitus among others believed that all substances had a single component.

It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The primary operations are comminution and concentration, but there are other important operations in a modern mineral processing plant, including sampling and analysis and dewatering.
