Associated gold in titanium zirconium sands placer «Central» (Tambov region)

Abstract

Аs a result of the study of titanium-zirconium sand placer Central set of methods found extremely uneven sporadic distribution of noble metal in the productive thickness. According to the assay-atomic-adsorption analysis of its content in enrichment products less than 0,01 g/t. Gold is thin (up to 0,1 mm) and ultra-thin (less than 0,1 mm), the morphology is varied. The largest number of characters corresponds to the fraction -0,05 + 0,03 mm. Large scales of gold have a thin clay shell, indicating their preservation from mechanical impact in the process of transfer. For smaller and thinner classes, high purity of gold is observed. Most often, gold marks are noted in productive sands with a relatively high content of clay fraction. Very low contents of the noble metal and poor recoverability by its gravitational methods indicate low prospects for the associated extraction of gold from titanium-zirconium sands.
