Shaker beneficiation
Shaking Bed Selective Mining
Selective mining is the process of extracting valuable minerals from a specific ore body. It is the practice of pulling out only the best ore that contains higher concentrations of valuable minerals while leaving the rest of the ore in place. Shaking bed selective min......
semi-countercurrent adsorption
Counter-Current Adsorption
Counter-current adsorption is a process used in chemical separations in which two immiscible solvent streams flow in opposite directions through a medium, such as absorbents or exchangers. It is commonly used in separations of multicomponent mixtures and often utilizes a......
solid-liquid separation
The Separation of Mixtures
A ‘mixture’ can be defined as a material containing two or more distinct substances that are not chemically combined. The aim of separating a mixture is to produce two or more individual compounds that are physically distinct from each other. To separate a mixture, th......
Interference settlement
Gravity is the force that keeps us on the planet, and interferometric gravity gradiometry (IGG) is a method of measuring the subtle acceleration of gravity on the surface of the Earth in order to better understand its effects around us. This technology has been used in many areas of research, incl......
Recovery rate
Recycling is an important way of reducing the amount of waste that is sent to disposal sites. Recycling keeps valuable materials out of landfills, prevents pollution and saves energy. By recycling, community members can also generate income and create jobs. Despite the many advantages of recycling......

Exploration and Sampling Techniques for Mineral Resources
Mining is an activity that has been undertaken for a very long time. Ancient civilisations dug deep into the Earth to find and extract a range of minerals and metals. This is a highly specialised exercise and in modern times, exploration a......
Strong magnetic field magnetic separator
Strong Magnetic Field Magnetic Selector
Magnetic separation is an important part of mineral processing and is used in the chemical and metallurgical industries for the recovery of valuable minerals from non-magnetic materials. During the past few decades, the traditional magnetic separation techn......
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 ......
centrifugal beneficiation
Centrifugal concentrator
Centrifugal concentrators are a class of gravity separation systems used to concentrate particles by their specific gravity. Centrifugal concentrators are most commonly used in the mineral processing industry, but they have also been used in coal preparation.
Centrifugal......
