Metallurgy
Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. In order to convert a metal oxide or sulphide to a purer metal, the ore must be reduced physically, chemically, or metallurgists are interested in three primary streams: feed, concentrate (metal oxide/sulphide) and tailings (waste).

The Journal of The South African Institute of Mining and Metallurgy JANUARY/FEBRUARY 1999 13 Introduction Assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold, the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and
Common Basic Formulas for Mineral Processing Calculations
· Pulp Densities. Pulp densities indie by means of a tabulation the percentages of solids (or liquidtosolid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.

Iron Ore Processing
This posed difficulty in producing concentrate with desired metallurgical performance. The modified strategy involved selectively recovering sinter fines with possible r ecovery of pellet grade material. Hence, the top size of the ore was kept at 5 mm and ore was subjected to scrubbing and washing, followed by classifiion.
Hausmannite: Mineral information, data and localities.
Hausmannite has a tetragonal distorted spinel structure (due to the JahnTeller distortion of the Mn 3+centred polyhedron). When heated above 1473 K, a cubic hightemperature phase appears (Frenzel 1980). Hausmannite generally forms black granular aggregates or, .

Rapid Analysis of Chromite and Chrome Ore
To distinguish between the mineral and the commercial ore, which is also commonly referred to as chromite, the ore is designated "chrome ore." Although the methods outlined here are described as being rapid, rapidity of execution was not the main critepon used in the selection of each procedure.
Extraction of Metals: From Ores, Definition, Meaning, Examples

The ores were ground into different particle size fractions. The size fraction of Wessels and Groote Eylandt manganese ores was 45 150 μm; CVRD and Gabonese ores were studied in the range 100 – 300 μm. Chemical composition of the ores was determined by XRF, as given in Table 1 (moisture and LOI were excluded).
