The different minerals have an effect on gold floatability and its recovery and they are influence by the gangue present in the ore. The particle size are variable such as 1 µm to 20 µm. The frequency, area and volume distribution of these grains indicate liberation, inclusion and possible formation of grain clustering.
ores and the compounding of metals to form alloys. Extractive metallurgy is the branch of metallurgical science & engineering which deals with the extraction and refining of metals from ores. An ore is a rock that contains commercially viable amounts of metallic/non-metallic solid minerals. Ores are complex associations of mineral grains
In the field of extractive metallurgy, mineral processing is the process of separating commercially valuable minerals from their ores. Mineral processing involves two major categories of processing.

Metallurgy: The scientific and technological process used for isolation of the metal from its ores is known as metallurgy. Gangue: The earthly or undesired materials which are contaminated with the ore are called gangue. Minerals: They are the naturally occurring chemical substances in the earth's crust obtainable by mining.
Economics of the industrial mineral s and rocks is shortly summarized in Table 1, and in the fact that 60% of all extracted mineral raw materials are nonmetallics representing 40% of the value of all solid raw materials.

minerals (e.g. Fe oxy-hydroxides) where deposited carbon in micro-pore spaces is difficult to remove. Application of this technique for primary base metal sulphide and iron ore minerals has proved successful. Figure 4 illustrates a coated polished section where the exposed mineral surface is free of carbon and the epoxy remains coated. The
Hence the mineral, bauxite is an ore of aluminium while china clay is not. The extraction of a metal of interest from its ore consists of the following metallurgical processes. (i) concentration of the ore (ii) extraction of crude metal (iii) refining of crude metal Malachite – copper mineral XII U1 Metallurgy - Jerald.indd 2 4/2/2019 11:26:53 AM
Mineral Processing is the art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue..

Impurities associated with ores are called gangue or matrix. Metallurgy The entire scientific and technological process used for isolation of the metal from its ores is known as metallurgy. Types of Metallurgical Processes 1. Pyrometallurgy Extraction of metals takes place at very high temperature. Cu, Fe, Zn, Sn, etc .. are extracted by this ...
Complex sulphide ores represent considerable reserves and resources in base non ferrous metals, in precious metals, and in sulphur. Some of their essential characteristics, which allow a general presentation of the complexity of their processing options, from the ore to the pure metals or finished products, have already been presented by the author (1,2).
2- rocks generally consists of variety of minerals. Mineral Vs Ore: ORE definition - natural aggregates of minerals from which a metal or metallic compound can be extracted economically and profitable. All ores can be minerals but all mineral cannot be an ore. Ore: is mixture of extractable mineral and extraneous rocky materials described as gangue

Used as an alloy and in stainless and heat resisting steel products. Used in chemical and metallurgical industries (chrome fixtures, etc.) Superalloys require chromium. It is
Metallurgy is the field of science which deals with the extraction of metals from ores which are naturally found in the environment. Most of the elements especially metals are presently combined with other elements and these are called minerals.
They are azurite and malachite, two of the ores of copper. The use of fire thus makes possible two significant new steps in the development of metallurgy: the casting of metal, by pouring it into prepared moulds; and the smelting of mineral ores to extract metal. Objects made from smelted copper, from as early as 3800 BC, are known in Iran.

The processes involved in the extraction of metal from their ores and refining is called metallurgy. The three steps of metallurgy are: 1)Concentration of ore. 2)Conversion of ore into metal. 3)Refining of impure metal. Concentration of ore The unwanted impurities such as sand,rocky material,earthy particles etc present in an ore are called gangue.

won from ores by the application of heat, in this case the heat of a wood or charcoal fire. Extract-ing copper from its ores is not an easy task. First the metallurgist must heat the ore to tempera-tures over 982 °C (1800 °F)—not an easy task with a wood fire—and second, the metallurgist needed something to contain the molten (liquid) copper.

The naturally occurring chemical substances in the earth's crust which are obtained by mining are known as minerals. Minerals which can be used as a source for commercial recovery of a desired substance are termed as ores. Earthy substance associated with ores are called gangue.
