procedures for obtaining ore samples

Ores and Minerals

The concentration of ore is the process of eliminating gangue from the ore Depending on the nature of the procedure it can be carried out in the following ways Gravity Separation This method is based on the difference in the gravities of ore and gangue particles Magnetic Separatio n A powdered ore is carried through a conveyor belt that runs over two rollers one …

Types of samplers used in soil sampling

 · Soil sampling is the process of obtaining samples of soil from the desired depth at the desired location in a natural soil deposit with a view to assessing the engineering properties of the soil for ensuring a proper design of the foundation The devices used for the purpose of sampling are known as soil samplers With the help of soil samplers various kinds …
