To start with, mineral thickener works on the principle of Gravity sedimentation and the most common construction of a thickener would be of iron or steel. The continuous thickener consists of a cylindrical tank. Pulp is fed into the centre of the tank via a feed-well placed up to 1 m below the surface of the suspension.

The main purpose behind comminution is to make the removal of minerals / materials from the ore or waste materials easier, as the particles are smaller and thus more exposed for further treatment. Main objectives of comminution: Increase surface area (increase the rate of reaction in further separation processes)

The process of comminution is the crushing and grinding of a material / ore to reduce it to smaller or finer particles. The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where mineral ore is broken down into small …

mineral processing is to adjust the size of mineral particles to adapt to the optimum size for the successive separation processes. Screens and classifiers are used to adjust the particles within prescribed and closer size

Jul 01, 2020 Comminution is performed for the reduction of particle size, and can be achieved by crushing and grinding. Crushing is performed on the large particles, and the grinding is performed on the particles smaller than about 50 mm. crushing The comminution process is the first step of mineral processing after drilling and blasting operations in the mine.
More Details
The first principle states that comminution calculations should be based upon the energy register of the feed and product, and that in any instance the specific energy input equals the energy register of the product minus the energy register of the feed.

Mineral processing is a major division in the science of Extractive Metallurgy. Extractive metallurgy has been defined as the science and art of extracting metals from their ores, refining them and preparing them for use. Within extractive metallurgy, the major divisions in the order they may most commonly occur are, Mineral Processing (or Beneficiation), Hydrometallurgy, …

Dec 26, 2015 In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

It presents the principles that govern various unit operations in mineral processing along with examples that illustrate how these principles apply to real-world situations. Topics are arranged in the order of the typical processing sequence, including comminution, separation, flotation, hydrometallurgy, and waste handling.

This chapter explains the process of comminution and its principles in mineral processing. Comminution theory is concerned with the relationship between energy input and the particle size made from a given feed size because most minerals are finely disseminated and intimately associated with the gangue, they must be initially “unlocked” or ...
