    IntroductionIron Ore ExtractionIron Ore ProcessingSintering and PelletizingAfter the iron ore has been prepared by crushing and grinding during ore extraction, the ore is actually processed. The aim of this is to reduce the undesirable high proportion of admixtures to a desired minimum in order to increase the iron content. This is done by processes such as flotation or magnetic separation. Subsequently, the milled ores are lumped by sintering or pelletizing in order to optimize chemical reactions in the blast furnace process. Ore processing (or ore dressing) is the separation of ir

    Gold Ore ProcessingMethods of Ore TreatmentAmalgamationConcentrationCyanidationGold-Milling 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 base-metal ores of equal dollar value. As a result, in many instances gold-mine development has been the advance guard of civilization in regions where other mineral resources were

    Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue
