The flotation reagents can be added in a feedforward fashion based on the plant raw coal tonnage. Automatic feedback control of the flotation reagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the froth cell tailings. Expensive nuclearbased sensors have been tried with limited success.

The present work aims to study the removal of iron from silica sand with oxalic acid. Based on the above mechanistic observations, an attempt was made to optimise the process parameters and reach a high degree of iron removal at minimum operating cost.
The market demands different silica sand quality according with diverse applications. Industries of flat glass, engineering stone and ceramic wants sand with iron contents and heavy minerals bellow 150ppm. The minerals content. Sands with 100ppm of iron content and 100ppm of heavy minerals are considered very high quality.
Heavy mineral sands ore deposits Wikipedia. The grade of a typical heavy mineral sand ore deposit is usually low. Within the 21st century, the lowest cutoff grades of heavy minerals, as a total heavy mineral (THM) concentrate from the bulk sand, in most ore deposits of this type is around 1% heavy minerals, although several are higher grade.
Silica / Glass Sand. Silica makes up about one fifth of the earth''s crust in igneous, metamorphic and sedimentary rocks, however, high purity, commercially available deposits are less frequent. It is generally mined as industrial, foundry or glass sands with its chemical impurities, size distribution and particle shape dictating end use.
