The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.

Ore | Processing, Extraction & Refining | Britannica
ore, a natural aggregation of one or more minerals that can be mined, processed, and sold at a profit. An older definition restricted usage of the word ore to metallic mineral deposits, but the term has expanded in some instances to include nonmetallics. Although more than 2,800 mineral species have been identified, only about …
What Is Mineral Processing in Mining?
What Is Mineral Processsing in Mining? Mineral processing is a form of extractive metallurgy that separates valuable minerals from the ore into a concentrated, marketable product. Mineral processing is also known as mineral dressing. Mineral processing is conducted at the site of the mine and is a highly mechanical process, with oversight from ...

mineral processing summary | Britannica
mineral processing, or ore dressing, Mechanical treatment of crude ores to separate the valuable mineral s. Mineral processing was at first applied only to ores of precious metals but later came to be used to recover other metals and nonmetallic minerals. It is also used during coal preparation to enrich the value of raw coal.

MINERAL PROCESSING
Introduction. Milling, sometimes also known as fine grinding, pulverising or comminution, is the process of reducing materials to a powder of fine or very fine size. It is distinct from crushing or granulation, which involves size reduction to a rock, pebble or grain size. Milling is used to produce a variety of materials which either have end ...
OVERVIEW OF MINERAL PROCESSING METHODS
It is a process of ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals. It is ...
Tin Ore Processing
The methods employed in dressing the tin ore up to the required percentage of purity depend mainly on the type of ore crushed. These may be briefly divided into two distinct classes—viz., a free milling ore and a complex milling ore. ... a free milling ore and a complex milling ore. In the former the ore is practically free from …

Chilean Mill
The Chilean Mill consists essentially of four heavy cast iron rollers with convex surfaces which are rotated on a concave surfaced die ring. The purpose of this design is to keep the ore between the crushing surfaces at all times, thus avoiding the necessity of scrapers to direct the ore into the crushing areas, and also to avoid spillage.
Iron ore mining and dressing
After the coarse ore has been extracted, it is crushed directly at the deposits with the aid of cone crushers or jaw crushers to more manageable sizes of approx. 15 mm. This is also known as lump ore. In addition to lump ore, fine ore (approx. 1 mm) and ground ore (ore powder) (approx. <0.1 mm) can also be obtained by crushing and grinding.

Ore Dressing
The particle size is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation.
