THE USE OF SULPHURIC ACID IN THE MINERAL SANDS Leaching of mineral sands is often referred to as a solid – liquid multiphase reaction. The mineral surfaces covered in iron oxide in the most stable form – Fe2O3 are contacted with sulphuric acid. This reaction involves sulphuric acid removal of the surface and the formation of iron sulphate – Fe2(SO4)3.

In this paper, we expose a novel processing method for the purifiion of sand silica. This method is a subsequent combination of thermal treatment and acid leaching.
Bioleaching of Iron Stained Silica Sands Sustainable To test the model intermediate scale laboratory column leaching experiments (150 kg) were carried out. The results of the project (both modelling and experimental) have shown that for certain types and levels of iron staining in sand, oxalic acid leaching using commercially produced acid can offer a real alternative to hot acid leaching.An efficient method combining thermal annealing and silica is subjected to thermal annealing in an infrared furnace followed by acid leaching. Thus obtained silica was ∗Author for correspondence ([email protected]) investigated by inductively coupled plasma atomic emission spectrometry (ICP–AES) method. 2.
