As the host rock was dolomitic limestone, fatty acid flotation tests were conducted on the rougher galena tails for the recovery of the lime-stone. Rougher flotation with 1.5 kg/tonne of sod. silicate and 1.0 kg/tonne of oleic acid emulsion, followed by two cleanings 0.5 kg/tonne of sod. silicate and 0.5 kg/tonne of oleic acid emulsion
Many countries around the world have abundant cement grade limestone deposits. But in cases where access to cement grade limestone is expensive or limited (for example – located in environmentally sensitive areas), a dry limestone beneficiation process such as STET can assist in generating a long-term supply of high-grade limestone from lower grade varieties.

There are two economic sources of lithium; brines and hard rock ores. The majority of the global lithium production, greater than 60%, is produced from brines while lithium ores accounted for the remaining production (Ebensperger et al., 2005).Table 1 summarises the world's major lithium producers from ores and brines, and the total reserves. The lithium …
With exponential demand of high grade lime stone both by cement and metallurgical industry of the region, beneficiation of lime stone is imperative to meet the specification for different industries.
