Classification of Mineral Deposits | Geology for Investors

Jul 30, 2013 · Most mineral deposits are formed by more than one process, so attaching a single label to them is difficult. Hence, there is a tendency to talk about Stillwater Complex type or Carlin-type gold deposits, which rather defeats the purpose of finding a general from the specific. There are two main approaches to mineral deposit classification.

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. 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 ...

About this site

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

4 Igneous Processes and Volcanoes – An Introduction to Geology

4.1.3 Igneous Rock Bodies. Igneous rocks are common in the geologic record, but surprisingly, it is the intrusive rocks that are more common. Extrusive rocks, because of their small crystals and glass, are less durable. Plus, they are, by definition, exposed to the elements of erosion immediately. Intrusive rocks, forming underground with larger, stronger crystals, are more likely to last.

The processes of formation of mineral deposits are grouped ...

This process of formation of mineral deposits has been described as pyrometasomatism by Lindgren and as contact-metasomatism by Bateman. In this case, the enclosing country rock is altered by the heat and other chemical constituents of the invading intrusive magma forming new minerals under conditions of high temperature and pressure.

Common Types of Spiral Classifier Used in the Mineral ...

Nov 20, 2019 · Mineral processing experts suggest that the single spiral classifier should be selected as far as possible under the determined processing capacity. According to statistics, the working load of the double spiral classifier is 0.6-0.75 times than that of the single spiral classifier, and

Classification of Mineral Deposits - Earth Sci

This subdivision, or classification, can be based on a number of criteria, such as minerals or metals contained, the shape or size of the deposit, host rocks (the rocks which enclose or contain the deposit) or the genesis of the deposit (the geological processes which combined to form the deposit). Since there is considerable debate among ...
