Methods 3120 and 3125 determine total silica. 4500-SiO 2.C D E and F determine molybdate-reactive silica. As noted in 4500-SiO 2.C.4 it is possible to convert other forms of silica to the molybdate-reactive form for determination by these methods. Method 3111D determines more than one form of silica.
Removal of hematite from silica sand ore by reverse flotation
Reverse flotation of hematite from a local silica sand ore has been investigated using a batch bench-scale mechanical flotation cell. The effects of various operating parameters such as type and concentration of collectors type of acid pH conditioning time solid-in-pulp concentration particle size and temperature have been studied on the hematite removal efficiency by reverse flotation.
