Separation of silica from pyrite cinder via reverse

sheet of open-circuit separation of pyrite cinder is shown in Fig.6, and the results are shown in Table 3.The results showed that the separation of silica from pyrite cinder by reverse flotation is possible and good selectivity can be achieved at about pH 8.2. Table 3 Results of reverse flotation of actual pyrite cinder ore (wt% )

Pyrite Mineral Uses and Properties

Pyrite as an Ore of Gold. The most important use of pyrite is as an ore of gold. The sulfide mineral content of the coal can be reduced by heavy mineral separation, but this removal is expensive, results in a loss of coal, and cannot be done with 100% efficiency. The sulfide minerals in coal and its surrounding rocks can produce acid mine drainage. Before mining, these minerals are deep

Flotation experiment research on a polymetallic sulfide ore of

sulfur but to improve the recovery of gold and silver when the pyrite content of the ore is low. Flotation separation of polymetallic sulfide ore is a very difficult process because of the complex mineral composition and closely related mineral paragenesis. Various research and data regarding the floatation technology and reagents have been conducted and obtained by numerous domestic and

Recycling of iron from red mud by magnetic separation

20/07/2014 A recycling process of iron from red mud by magnetic separation is proposed, in which iron oxide (Fe 2 O 3) in red mud transforms to magnetite (Fe 3 O 4) by anaerobic co-roasting with pyrite (FeS 2).TG-DTA and XRD results showed that hematite was reduced to magnetite by the thermo-decomposed compounds (iron monosulfide, pyrrhotite and element sulfur) of pyrite.
