The recent advances of flotation for lead oxide ores have been reviewed from the flotation technological flowsheets and flotation reagents in this paper.

Aiming at a low-grade complex lead oxide ore with deep oxidation and high content of silicon in Yunnan province,ethyl thio carbamate and new collector LW13 was used in flotation of galena and lead oxide ore respectively.

Based on the characteristics of a lead-zinc oxide ore, the flotation process used Na 2CO 3 as the regulator to control pH, float lead oxide minerals after sulphurating, then float zinc oxide minerals used combined amine collector ZP-05 as collector of zinc oxide ore is pointed out in this paper, the lead concentrate assay 40.

Technological-mineralogical analysis of carbonate rock type oxidized lead-zinc ore shows a complicated mineral composition and dissemination relation.

By determining the gold leached directly from a typical clay high oxidized ore in Zhengfeng County (Guizhou Province), and estimating the effects of adhesive and No.

This paper deals with a pilot study for recovery of copper from refuse of dressing plant, from low-grade ore and from refractory oxidized ore using heap leaching,extraction,and electrodeposit techniques.
