soil concentrate floatation tailings

Recovery of pyrite from copper tailings by flotation

After 10 min of flotation, the instantaneous and accumulated grade of pyrite in the concentrate is 11.2% and 51.1% respectively; therefore, a flotation time of 10 min was set for the rougher stage. The rougher tailings with a pyrite grade of 0.43% will be reprocessed in a scavenger flotation stage.

Pyrite Tailings Recovery by Flotation

Pyrite has long been used as a source of sulphur, and its recovery as a by-product from the flotation of certain base metal ores is a well established practice. Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite. In many instances these tailings can be treated to yield pyrite concentrates that are a

We want to gold recovery by flotation (now we have a recovery 70% of gold) then maybe roasting tests to finally cyanidation and recovery gold.

Tailings Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

Flocculation and Sedimentation of Bauxite Flotation

Flocculation and sedimentation of fine bauxite from flotation tailing pulp were studied using different flocculants to investigate the possibility of its application. The results of this investigation indicate that inorganic flocculants of PAC and PAS have better flocculating effect than organic flocculants of PAM1# and PAM2# when keeping the original pH (7.5~8.0) of tailing pulp, however its

Rare Earth and Phosphorus Leaching from a Flotation

This study focused on the effects of wet-process operating conditions on REE and phosphorus leaching from a kind of flotation tailing of Florida phosphate rock. The tailings were first beneficiated with a shaking table, and then a series of leaching tests were conducted on the shaking table concentrate. The results indicated that REEs had
