The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Crushing is the process of reducing the size of materials so that they can be further processed. In addition to being used in the chemical industry, industrial crushing equipment can be very useful in a variety of businesses. These include, but are not limited to, waste and recycling, mining, food processing, construction, and coal.

In the process of mining ore benches are developed for the purpose of drilling, blasting and hauling of the ore to the crushing plant. The height of the benches is dependent on several factors such as output requirement, shape, size and depth of occurrence of ore body, geological disturbance suffered by the ore body, hardness and compactness of the ore body, type and the size of deployed for

CHAPTER 4: MINING WASTE. This chapter covers the different types of mining waste, how they are formed and how they are disposed of or used. Mining operations can generate enormous amounts of waste (i.e. waste rock and tailings) that must be managed and handled in a way that avoids negative environmental impact.

This process reduces large run-of-mine lumps into smaller pieces, making them easier to handle, and releases or liberates the diamonds to be recovered in subsequent steps. Crushing is done in stages to “gently” free the diamonds from the kimberlite rock and produce a target size, usually less than 25 mm, for further processing.

Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along

The mined rock is transported to the processing site and stockpiled. The material then is crushed. Depending on the degree of cementation, several stages of crushing may be required to achieve the desired size reduction. Gyratory crushers, jaw crushers, roll crushers, and impact mills are used for primary and secondary crushing.

Mining of raw materials is a process that consists of several stages. In open-pit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive strength is extracted by e. g. a bucket wheel excavator. Most important influencing factors for crusher decision are compressive strength, moisture content, capacity of crusher, abrasiveness

In industry, crushers are machines which use a metal surface to break or compress materials into small fractional chunks or denser masses. Throughout most of industrial history, the greater part of crushing and mining part of the process occurred under muscle power as the application of force concentrated in the tip of the miners pick or sledge hammer driven drill bit.
