Bubble mineralization
Bubble mineralization is a process by which mineral particles are concentrated in cavities created by the escape of dissolved minerals from shallow pockets of water into the surrounding, permeable rock matrix. This process is particularly important in the precipitation of zinc, iron, and other met......

mineral crystal structure
Introduction
Minerals are naturally occurring inorganic solid substances made up of atoms, molecules, or ions held together by chemical anchors and organized into regular three-dimensional crystal structures. While many are known and identified, there are still unknown minerals or undiscovered co......
Platinum group metal ore beneficiation
Platinum group metals (PGM), comprising mainly platinum, palladium, rhodium, iridium, osmium and ruthenium, are of great interest to the mineral industry, due to their unique physical and chemical properties and wide range of applications. These metals are non-ferrous and have a very high melting ......
Vulcanization roasting
Introduction
Sulfidation roasting is a chemical treatment process for producing a range of products. This process involves the partial oxidation of certain minerals, usually sulfides, to form a mixture of solid and liquid products. The sulfur present in the original mineral is oxidized to sulfur ......
Mineral Floatability
MINERAL FLOATABILITY
Mineral flotability is an important mineral processing application that is used to separate particles by differential behavior in waters. Flotability is usually favorable if a mineral’s own hydrophobicity is increased and the particle’s attachment to water is decreased. Flo......
mineral permeability
Mineral magnetic susceptibility
Magnetic susceptibility is a measure of the response of a material to an externally applied magnetic field and is expressed in terms of the ratio of the magnetization induced in the material to the strength of the applied field. It is a fundamental property of a ma......
Rammelsberg mine
Ramelsberg Mining
The Ramelsberg mining area has a long and varied history, with mining of copper, silver, and gold stretching back more than 800 years. Mining in the area ensued first with surface mining, followed by open-pit mining, and finally, underground mining. This makes the Ramelsberg min......
Diagnosis of Air Leakage in Sintering Production
Diagnosis of the Leakage of sintered Production
Introduction
In production process, the leakage of sintered production is a common problem. It can be reflected by the variations of quality and output, and understood through the production process. The leakage phenomenon mainly includes the depos......
Precipitation and smelting of bismuth sulfide concentrate
Bismuth sulfide is a mineral ore that is rich in bismuth and is the primary source of bismuth for chemical and industrial applications. Bismuth sulfide is originally found in a naturally occurring combination with various metals such as lead, tin, and copper, as well as with other sulfide minerals......
rocks and rock masses
Rocks and rock masses are in the Earth’s high pressure, high temperature environment and combined with the effects of long-term weathering and erosion. It is an important mineral raw material forming the surface crust and mantle of the earth, and plays an important role in the circulation of the ......
