Iron Recovery from Hematite Tailings by a Novel HGMS ...
A novel HGMS-Centrifuge process is proposed to recover iron values from a low-grade hematite tailings. In this process, the tailings is effectively roughed with pulsating high pulsating high gradient magnetic separator to produce a relatively high-grade iron concentrate, then this concentrate is cleaned with a continuous centrifugal concentrator to produce a high-grade iron concentrate.

Hematite - Wikipedia
Mine tailings. Hematite is present in the waste tailings of iron mines. A recently developed process, magnetation, uses magnets to glean waste hematite from old mine tailings in Minnesotas vast Mesabi Range iron district. Falu red is a pigment used in traditional Swedish house paints. Originally, it was made from tailings of the Falu mine.
Gold recovery from calcined tailings - Hydrometallurgy ...
The material is the waste product from an Edwards roaster. The host ore is arsenopyrite - very refractory. Normal cyanidation (at elevated temperature levels) only recovers 30% of the gold. Biox does not work. All help will be greatly appreciated.
Hematite Processing by Flotation
Hematite Processing by Flotation. Direct shipping of high grade iron ore, because of depletion or partial depletion of reserves, or high costs of operation has forced operators to use some means of beneficiation to produce an acceptable product with the lower grade iron ore reserves.
New approaches for extracting and recovering metals from ...
A two-stage mineral leaching and metal recovery protocol was developed to extract copper from tailings generated as waste materials in two mines currently operating in Spain and Serbia.
Performance of a full-scale continuous centrifugal ...
Pulsating high-gradient magnetic separation (PHGMS) of fine hematite from tailings was studied using a pilot PHGMS separator to investigate the possibility of its application in industry.
Re-Processing Gold Tailings in South Africa
