Experimental research on comprehensive recovery of the Sn-Cu-Pb-Zn polymetallic ore

the Tin-polymetallic Ore had high value,containing many valuable metallic mineral such as tin,copper,lead,zinc.In order to callback the associated minerals such as copper,lead,zinc,the technological flow sheet of copper-Plead partial bulk flotation was adopted and finally the comprehensive recovery of copper,lead,zinc and sulfur was realized,among which the grade of copper,lead,zinc and sulfur was 23.49%,56.22%,47.09%,37.75% and their recovery was 85.98%,80.77%,87.21% and 74.20% respectively.At the same time,the associated tin in tailing was concentrated and its total recovery was 89.33%.reaching the aim of comprehensive recovery to associated minerals such as copper,lead,zinc.
