Feb 13, 2019· | 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.
The principle is to exert an impressed current on the metal surface. ... It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials. ... fixed cone discharge valve, butterfly valves and ball valve. The nominal diameter ...
The extractive metallurgy of tin is complicated by tin''s affinity for iron, and by the need to achieve good metallurgical recovery because of tin''s high unit value. Tin has a low melting point of 232 °C, but the smelting temperatures needed are quite high. Figure 1 shows the range of tin processing options.

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.
Pyrometallurgy is a branch of extractive consists of the thermal treatment of minerals and metallurgical ores and concentrates to bring about physical and chemical transformations in the materials to enable recovery of valuable metals. Pyrometallurgical treatment may produce products able to be sold such as pure metals, or intermediate compounds or alloys, suitable as feed for ...
Ball Mill Mineral Processing And Extractive Metallurgy Lecture. Mineral Processing Equipment: ball mill mineral processing and extractive metallurgy lecture A type of mining equipment that can trigger the development and change of the beneficiation technology main core machines are ball mills, rod mills, flotation machines, magnetic separators, etc.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.

Types of Crushers Mineral Processing Metallurgy. Crushers may be divided into three general classes, with respect to the manner in which they do their work: Pressure Crushers: This category embraces the several types of gyratory crushers and jaw crushers, as well as the double crushing rolls, with either smooth or corrugated shells.
Extractive metallurgy as a discipline deals with the extraction of metals from naturally occurring and man made resources. Separation is the essence of metal extraction. Development of efficient separation schemes calls for a through understanding of extractive metallurgy principles in
What is Extractive Metallurgy ? Deals with extraction of metals from its naturally existing ore/minerals and refining them Minerals: Inorganic compounds with more than one metal in association with nonmetals like S,O,N etc. Naturally existing minerals are sulphides, oxides, halides like: Hematite (Fe2O3), Magnetite (Fe3O4), Chalcopyrite (CuFeS2), Dolomite
