Thickening of Mineral Processing Products | SpringerLink
In mineral processing plants, thickening is intended to remove the water content of pulp so that the mineral processing products meet the requirements of the other processes. Usually the solid mass fractions of concentrate and tailings are 30–40% and 8–20%, respectively. After thickening, the solid mass fraction of concentrate can be 65 ...

Mineral Processing
Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Microencapsulation of vitamins in food applications to prevent losses
Vitamins are chemically reactive compounds. During food processing and storage, the stability of many vitamins is affected by chemical and physical factors such as light, temperature, pH and oxygen levels (Gregory, 2008), leading to significant nutrient losses in the end products such as canned products (Rickman, Barrett, & Bruhn, 2007).To prevent these …

In order to increase the recovery of PGMs by flotation, it is necessary to optimise the liberation of the key minerals in which the platinum group elements (PGEs) are contained which include sulphides, arsenides, tellurides, and ferroalloys among others, while at the same time ensuring the optimal depression of gangue minerals. In order to achieve this, comminution …
