Mineral processing can involve four general types of unit operation comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes, which is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle

In all of these processes, the most important considerations are the economics of the processes, which is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smaller the particles processes, the greater the theoretical grade and recovery of the final product, but this is difficult to do with fine particles since they prevent certain concentration processes from occurring.
Comminution is particle size reduction of materials. Comminution may be carried out on either dry materials or slurries. Crushing and grindingare the two primary comminution processes. Crushing is normally carried out on "runofmine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding. The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, usually closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant.

Flotation cells can be used in the coarse separation and scavenging of ores with simple composition and higher grade, and its advantages are simple structure, small footprint, easy to maintain and operate, etc.
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic conditionthat is, the surfaces are either repelled or attracted by water.The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants.

Flotation is an economical and effective separation of refined gold technology, especially for these ores that are not suitable for other processes, such as goldbearing copper ore, base metal ore, coppernickel ore, platinum group ore, etc. Flotation is also used to remove impurities before hydrometallurgical treatment (ie, carbon preflotation) to purify lowsulfide and refractory ores for further processing.

Main Separation Methods of Various MineralsTest SchemeSelection of Test SchemeXanthate flotation after vulcanization.The method is to sulfurize oxidized minerals with sodium sulfide or other sulfurizing agents (such as sodium hydrosulfide), and then flotation with highgrade xanthate as collector. Copper oxide minerals that can be treated by vulcanization, mainly copper carbonates, such as malachite and azurite, can also be used for flotation of hematite. If silicomachite is not specially treated in advance, its vulcanization effect is very poor or even can not be vulcanized. Fatty acid flotation method
Gold Ore ProcessingMethods of Ore TreatmentAmalgamationConcentrationCyanidationGoldMilling DataThe fact that a product of high value and small bulk can be produced at a gold mine, often by relatively simple milling processes, has made it possible to operate gold mines successfully in remote and inhospitable regions where high costs of transportation, fuel, and power would make it impossible to exploit profitably basemetal ores of equal dollar value.
