  • Coal preparation plantWikipedia

    A coal preparation plant (CPP also known as a coal handling and preparation plant (CHPP) coal handling plant prep plant tipple or wash plant) is a facility that washes coal of soil and rock crushes it into graded sized chunks (sorting) stockpiles grades preparing it for transport to market and more often than not also loads coal into rail cars barges or ships.

  • Eco-efficient and cost-effective process design

    A significant fraction of iron ore used in steel production comes from magnetite deposits. Magnetite iron ore requires significant beneficiation which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix. And grinding consumes a lot of energy. This article investigates eco-efficient alternatives for the process design for magnetite iron ore.

  • Specific Gravity and Bulk Density Mining SGS

    "Specific gravity" is the density of a material relative to water. Since rocks are comprised of several distinct mineral phases they do not have a fixed specific gravity. Instead a rock s "bulk density" arises as a result of the percentage of all minerals in a sample multiplied by the specific gravity of each.
