PRELIMINARY STUDIES EXTRACT GOLD FROM THE TAILINGS OF DIAMONDCONTENTS SANDS
Presents the results of preliminary experimental data the study of processes associated gold recovery steeply inclined hub in the extraction and beneficiation of diamond- contents sands compared to gateway small filling. The enrichment was subjected Sands class -1 mm with a low gold content from 5.5 to 33.4 mg/m3 while gold is mainly represented in classes size -0,25+1.25 mm 52% and -0,125+0 mm 23.5%. Just made 10 large-scale experiment with different performance, purging time of discharge of the concentrate, the flow rate of flush water to perejitye plate and the drive of the concentrate. The best result was obtained with extraction 45,65% when the concentrate is 0.42%. This positive result is a high performance and reduction ratio. The next stage of research associated with improving the quality of extraction of gold.
