unit operations carried out during mineral ore dressing

Dhaubadi Iron Company Limited

In mineral processing, a number of unit operations are required to prepare and classify ores before the valuable constituents can be separated or concentrated and then forwarded on for use or further treatment. The field of mineral processing has also been given other titles such as mineral dressing, ore dressing, mineral extraction, mineral ...

Mineral processing news and technology • BulkInside

Important unit operations include: Comminution / Size Reduction. To achieve the goal of recovering valuable materials, the raw ore must be reduced to fine size prior to separation. This process is called 'comminution' or 'size reduction'. Comminution may be carried out on either dry materials or slurries.

CHAPTER 1 MINERAL DRESSING - Webs

During ore dressing, the crude ore is reduced in size to a point where each mineral grain becomes essentially free so as to make separation between them. Such a phenomenon of making the mineral grains free from gangue in an ore is termed as liberation. This is practically carried out by size reduction performed by crushers and grinding mills.
