Definitions and types The Concise Oxford Dictionary defines the verb condition to mean bring into desired state or condition. This definition applies and extends to conditioning of ores for flotation. The term is loosely used to describe any preparatory stage prior to flotation. Different systems require conditioning for different purposes: while one mineral may require a title=Ore

Mine-run ore is initially crushed and sized in a series of crushers and vibrating screens to approximately minus 5/8 in. Crushed ore is then ground in rod mills and passed through cyclones. The oversize is ground in ball mills, then pumped back to the cyclones to achieve a minus 200 mesh flotation feed.

The upper limit of the ore particle size is related to the ore size, embedding characteristics and equipment size. In usually, the ore is 50-150mm, and the coal is 300-500mm. DMS can greatly reduce the surrounding rock and waste rock under the same processing capacity, reduce ore grinding consumption, thus reduce production costs.

The zinc ore was considered to be a product from a rod mill rather than the feed to the mill, although its origin was not specified. The ores were reduced in size by wet ball milling just before each flotation test (500 g minus 1/4—inch ore, 750 ml H 2 0, 8025 g steel balls).

Slime is detrimental to every type of flotation, and iron ore flotation is no exception because iron ores contain more slime than m a n y or ores. Slimes cause a difficult recovery problem in flotation of iron minerals, and if present in quantity, result in a lowering of concentrate grade when employing silica flotation methods.

Aug 25, 2020Concentration of ores may be achieved by froth flotation in which an ore is contained in a froth that floats at the top of a water vat. After the ore has been concentrated it must be roasted to a high temperature allowing for the desired metal to be oxidized. Once the metal is oxidized it is reduced by a reducing agent.
