basic objectives of ore dressing

  • Mineral processing Wikipedia

    In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores History. A set of Cornish stamps. This section needs expansion. You can help by adding to it. (August 2010) Before the advent of heavy machinery the raw ore was broken up using hammers wielded by hand, a process called "spalling

    Ore Dressing Sympatec

    Ore Dressing. Real-time monitoring of grain size and concentration in ore slurries. The extraction of raw minerals begins with the mining of rich ores, which are then cut up in crushers and grinders. The pieces of rock initially weighing tonnes are ground down to a few tenths of a millimetre. This grinding process, which often covers six decimal orders of magnitude of the particle size, is

    CHAPTER 1 MINERAL DRESSING Webs

    The objectives of mineral dressing are as follows: 1. To eliminate unwanted chemical species: To prepare the ore particle from chemical stand point, primarily involving the following steps: a. Liberation of dissimilar particles from each other appearing in the bulk ore. b. Separation of chemically dissimilar particles. 3 2. To prepare ore from physical standpoint. This involves: a. Reduction

    SIMULATION OF ORE DRESSING PLANTS THE BASIC PRINCIPLES

    * Ore dressing plants are collections of unit operations connected by process flow streams that transmit material from one unit to the next. The flow of materials is directed by the flowsheet structure. * Each unit operation processes its own feed materials and will separate it or transform it in accordance with the specific objective of the unit. 3 * The behavior of the plant as a whole
