For example: Chromites ores [1]. These are classified into three grades: Metallurgical Ore with a high chromium content (minimum 68% chromium) and the chromium/iron ratio must not be less than /1, will be suitable for the manufacture of ferrochrome alloy or chromium metal. Table 1: Metallic minerals for other uses than metal production.

Gold extraction Gold extraction

Gold extraction

For most freemilling ores, a pretreatment process is necessary when chemical recovery is being employed. The gold is not sufficiently liberated as is the case with placer ores, and therefore crushing and grinding is required to allow the cyanide to access gold components. Permeability is the major indior of how much communition is required prior to leaching. Although there are various ...

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 ...
