fragmentation, Determination method ABSTRACT The article summarizes scientific and industrial research of blast fragmentation patterns in different mining and geological conditions. Particle size distribution in a bulk is one of the most important parameters for ore mining as it significantly affects further production process and profit return.
Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.
#0183;#32;Typically, it is a lower cost mining method, meaning lower grades of ore are economic to mine. Underground mining occurs when the ore body is too deep to mine profitably by openpit. In other words, the quality of the orebody is high enough to cover the costs of complex engineering underneath the Earths crust. When Technicals and Quality
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 engineering characteristics of tailings are in most instances influenced by the degree of thickening and the method of deposition. It is therefore essential that while investigating the properties of tailings that the physical characteristics and material parameters ( beach slope angles, particle size segregation, water recovery) that can occur as a result of varied deposition

The objective of this lesson is to provide the details of size reduction methods involved in The el ectric power consumption by this process run on ore mining . Comminution is particle
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.
The particlesize distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
2. Size Distribution Analysis Using Digital Image Processing Measurement of fragment size of blasted rock is considerably important in order to evaluate the efficiency of the production blasting operation. There are several methods of size distribution measurement and fall under two broad categories; direct method and indirect methods.
#0183;#32;Underground mining method selection is one of the most important decisions that mining engineers have to make. Choosing a suitable underground mining method to extract a mineral deposit is very important in terms of economics, safety and productivity of mining operations.

#0183;#32;The values of quot;dquot; are the diameter of the largest particle of ore to be sampled. I have found that it can be useful in sampling, when used by pesonnel that understand the ore, and sampling, The table, above, relates the particle size of the material being sampled to the sample size required for a representative sample.
