Onstream particlesize analysis In mineral processing, an excessively large mean particle size results in inefficient extraction of the wanted materials whilst overgrinding is timeconsuming and expensiveThe slurry that remains after this process has a very fine particle size Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand) Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to ‘see’ the gold in the leaching processOre processing – Waihi Gold with a particle size of 60 m to generate a product with a particle size of P80of 32 m at a throughput of 300 t/h The Karara magnetite concentrator in Western Australia has four TowerMills (ETM 1500) installed for tertiary grinding dutiesBeneficiation of Magnetite Ores

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 Furthermore, flotation cells are sensitive to processing of an ore These tests are performed such that they replicate, on small scale, the fullscale flotation flow sheet To incorporate the effect of recycle streams, they are often performed multiple times with the recycled streams from a previous test added at the appropriate place in the subsequent test It is assumed in these types of testing that the selectivity and recovery Particle Size Distribution Effects that Should be Determination of particle liberation size Considering the mineralogical data for each ore, the samples were ground under 1 mm, classified, and the liberation degrees of chromite and gangue minerals were determined by the particle counting method using a binocular microscope In thisGrinding Size Estimation and Beneficiation Studies Based

Establishing thE ProcEss MinEralogy of gold orEs
From the perspective of metallurgical processing, gold ores can be classified into freemilling and refractory ores Their extractive metallurgy are largely driven by mineralogical factors such as: gold particle size, association with other minerals, coatings and rimmings, presence of cyanicides, oxygen consumers and pregrobbers, presence of refractory gold minerals and locking of
