Resumo
A new process of catalytic autoclave desiliconization of the leucoxene concentrate by lime milk with the formation of synthetic rutile and wollastonite is developed. The general laws of the processes occurring under the conditions of pressure leaching of the concentrate are revealed, and the main leaching parameters that ensure selective desiliconization of leucoxene grains are determined. The leucoxene concentrate is shown to contain rare and rare-earth elements. They are concentrated in synthetic rutile during desiliconization, which facilitates their extraction during subsequent chlorination of rutile.
