    Mining techniques usually consist of two types based on excavation methods. These are surface mining and underground mining (sub surface mining). Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods.

    Mineral processing sampling methods Sampling can be done in a simple way, which is collecting some portions of materiel from different locations; or when the ore is transported in wagons or conveyor belts. After that we can mix all portions to form one large sample for measurement and test work. This called the grab sampling.

  • Sampling in the South African minerals industry

    The term ‘sampling’ here is taken to include all types of sampling in the minerals industry, from face or chip sampling of solid ore in mining operations, through cross-belt, cross-stream, or cross-ram sampling of streams of broken ore or slurry, sampling of cuttings from reverse circulation or blast-hole drilling, to the collection of dust and fine particulate products of drilling and rock cutting.

  • Grade Control SpringerLink

    Abstract. In some mining operations, one of the most important roles played by the geologist is the supervision of grade control. In an open-pit operation, this involves the sampling of blast-hole cuttings produced by down-the-hole hammer drills and the classification of bench reserves into ore, low grade or waste material, or into various metallurgical types.
