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 smallenew content will be added above the current area of focus upon selection

comminution is particle size reduction of materials. comminution may be carried out on either dry materials or slurries. crushing and grinding are 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. crushing is a dry process whereas grinding is generally performed wet and hence is more energy intensive.
sizing is the general term for separation of particles according to their size.
the simplest sizing process is screening, or passing the particles to be sized through a screen or numb · text under ccbysa licensechapter 1 mineral dressing webstermed as ore dressing or mineral beneficiation. so mineral dressing or ore dressing is commonly regarded as processing of raw ores to yield marketable products by such physical means those do not destroy the physical and chemical identity of the ore. 1.2. economic justification of mineral dressing 1. to purify and upgrade the oremining mineral processing (or mineral dressing) is a specialized area in the science of metallurgy that studies the mechanical means of crushing, grinding, and washing that enable the separation (extractive metallurgy) of valuable metals or minerals from their gangue (waste material).mirlmineral processing processing strategies for all types of ores, improving recoveries, fine particle separation. mine ventilation ventilation design and arctic issues. ground control rock and soil testing underground structure. mineral economics reserve estimation, overview of mineral processing methodsthe first process that most of the ores or minerals undergo after they leave any mine, is mineral processing or mineral/ ore dressing. it is a process of ore preparation, milling, and ore dressing...author a. balasubramanian

'mineralogy' is the scientific study of minerals and 'mineral processing' is the production of concentrates from ores. 'process mineralogy,' however can be defined as the practical study of minerals associated with the processing of ores, concentrates and smelter
