Flotation separation of valuable minerals BOC Gases

A process for separating minerals of different mineralogical character. A milled slurry or flotation concentrate is subjected to a first conditioning step (20) followed by a first flotation step (30) followed by a second conditioning step (50) followed by a second flotation step (60).One of the conditioning steps is with an oxidising gas, the other of the conditioning steps being with a non

Flotation separation on rare earth minerals and

The flotation process of native rare earth minerals such as bastnasite, monazite, mixed minerals of bastnasite and monazite, using the new effective collector Dh was studied, respectively, and the

Interactive effect of minerals in the flotation of complex

2020-2-12  Abstract: Froth flotation is the most effective industrial method used for the separation of fine-grained minerals. The main problem for the flotation of complex ores, obviously, is the negative effect of the interactions among minerals in slurry, which leads tothe variation of surface properties in the process of separation. In this review,

Flotation behavior and separation mechanism of quartz

2018-7-10  flotation conditions on the flotation behavior of quartz, hematite and magnetite under reverse anion flotation system were investigated by pure minerals flotation tests with the new type collector α-BLA. The separation mechanism of quartz from hematite and magnetite was studied by contact angle, zeta-potential and infrared spectroscopy. 2.

Flotation separation of chalcopyrite from galena by

2016-1-20  3.1.3 Flotation of chalcopyrite and galena with APS as depressant Sodium persulfate is often used as a strong oxidant. In the separation of copper/lead minerals by flotation, APS can be used as the depressant of galena. The effects of APS on the recovery rates of chalcopyrite and galena at pulp pH=6.5 were determined (see Fig. 5). The results

Mineral processing Wikipedia

2020-10-13  Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

1). Flotation is a selective process and can be used to achieve specific separation from complex ores such as lead-zinc, copper-zinc, etc. Initially developed to treat the sulphides of copper, lead, and zinc, the field of flotation has now expanded to include the oxidized minerals, non-metallic ores and fine coal.
