Sometimes the final flotation stage is omitted, leaving a feldspar-silica mixture (often referred to as sandspar), which is usually used in glassmaking. From the completed flotation process, the feldspar float concentrate is dewatered to 5 to 9 percent moisture. A rotary dryer is then used to reduce the moisture content to 1 percent or less.

May 21, 2020· Therefore higher iron ore feed content to blast furnace is always preferred. Indian hematite, though rich in iron content has a higher content of alumina and lower silica content. Alumina to silica ratio is as high as 1.5–3%. Adverse alumina to silica ratio is detrimental for the blast furnace. This should be less than 1.5 and preferably below 1.
The silica present in the bauxite tends to be concen-trated in the finer grained fractions, and this charac-teristic makes bauxite amenable to beneficiation by screening techniques. Pearson' has reported that in a bauxite of average composition of 1.58% silica, the minus 100 mesh fraction analysed a silica content as high as 10.30%.
