In general, the lower the concentration or percentage of ore in the parent rock, the greater the amount of processing needed to recover the ore and the finer the particle size of the resultant tailings Some ores, such as iron ore, are found in relatively high percentages and are fairly easy to separate

Feb 15, 2005· Process engineering: Particle size reduction techniques and equipment There are numerous industries that depend on size reduction to improve performance or to meet specifications This article details size-reduction techniques and equipment that may assist you when handling these materials By J Peter Clark Feb 15, 2005
In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore
Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine , It has a much smaller particle size than ore fines and cannot be .
Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling
liberation of metal from the ore The benefits are particularly noticeable in the heap leaching process, where the POLYCOM® product demonstrably increases the yield and thus the operating economy of the facility POLYCOM® particle size distribution The economic and gentle processing solution Particle size [mm] Material passing screen .

The purpose is to break the valuable mineral grains free of the gangue minerals, so that they can be physically separated from each other This makes it possible to produce a pure mineral concentrate using processes like froth flotation or magneti.
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy
of the Merensky ore, where approximately 934% of the variance in the particle size distributions could be explained With fewer data available, the variance in the particle size distributions in the UG2 ore could be explained less accurately (824%), but still satisfac-torily In addition, smaller particle sizes (less than 300 µm) could be
The particle size is of particular importance in this process If the particles are too large, unwanted accessory minerals cannot be separated from the ore The ore concentrate obtained only has a low purity Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation
The mineral species to be found can be free gold, pyrite or tellurid The different minerals have an effect on gold floatability and its recovery and they are influence by the gangue present in the ore The particle size are variable such as 1 µm to 20 µm
measuring particle size before and after the process Particle size growth may be monitored during operations such as granulation or crystallization Determining the particle size of powders requiring mixing is common since materials with similar and narrower distributions are less prone to segregation

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 .
Guthrie said the second case – sorting of ore to increase grade and reduce subsequent processing and transport costs – is generally only economically favourable if the processing and ore transport costs are high (in relation to head grade) and the recovery of values is also high (eg >95%)
