Description
Technical field
The present invention relates to a kind of comprehensive recovery method of gold ore resource containing molybdenum multi-metal, belong to metal selecting and smelting technology field.
Background technology
At present, what mainly adopt when containing the ore dressing of molybdenum multi-metal gold mine is single method for floating, preferentially selects molybdenum, more plumbous, the sulphur of choosing, press down the floating molybdenum of copper, guarantee concentrated molybdenum ore, inhibitor and pore forming material interact, and medicine sorts difficulty, the metal separation grade is low, and treatment capacity is big, and the rate of recovery is low, is difficult to reach the anticipation effect; And the backwater in the floatation process directly discharges, and has badly influenced surrounding environment.
Summary of the invention
The object of the present invention is to provide a kind of comprehensive recovery method of gold ore resource containing molybdenum multi-metal, with elements such as the valuable metal gold and silver in the comprehensive recovery mineral, molybdenum, lead, copper, sulphur.
To achieve these goals, technical scheme of the present invention has adopted a kind of comprehensive recovery method of gold ore resource containing molybdenum multi-metal, may further comprise the steps: (1) will contain the molybdenum Gold Ore earlier through traditional technologys such as muck, ore grindings, adopt full bulk flotation method again, with the useful metallic elements flotation is collective concentrate, and mine tailing is discarded; (2) collective concentrate adopts CCL charcoal slurry wet method gold-leaching technology, leaches and reclaims gold and silver; Soaking mine tailing behind the gold is used for next step and preferentially selects molybdenum; (3) soak golden mine tailing through preferential separating flotation molybdenum, obtain qualified concentrated molybdenum ore; (4) select the molybdenum mine tailing activated after, separating flotation lead obtains lead ore concentrate again; (5) select plumbous mine tailing to select copper through separation again, obtain copper ore concentrates; (6) select the copper mine tailing again through selecting sulphur, obtain the sulphur concentrate, select the sulphur mine tailing after filtration, backwater circulation is applied to charcoal slurry wet method and soaks gold, reclaims gold and silver.
The medicament that bulk flotation in the step (1) adds is: sodium sulfate 500~1500g/t, water glass 500~1000g/t, Sodium hexametaphosphate 99 500~1000g/t, kerosene 200~500g/t, sodium oleate 100~300g/t, xanthate 50~100g/t, copper sulfate 100~200g/t, No. 2 oil 50~150g/t.Adopt bulk flotation, reclaim useful metal in the raw ore to greatest extent, meet " early receive and early abandon " principle fully.
Mine tailing in the step (1) is useless mineral such as silicon-dioxide.
Charcoal slurry wet method in the step (2) is soaked the medicament that adds in the golden process and is: lime 2~8Kg/t, yellow soda ash 5~15Kg/t, sodium hydroxide 5~10Kg/t, sodium cyanide 3~7Kg/t, hydrogen peroxide 300~500g/t and gac 1~60Kg/t; Charcoal slurry wet method is soaked the metal working preface and has promptly been reclaimed the precious metals such as gold and silver in the collective concentrate, separates with copper, lead for next step molybdenum again, presses down the floating molybdenum of copper and lays the first stone.
The medicament that adds in the separating flotation molybdenum process in the step (3) is: tannin extract 200~800g/t, kerosene 200~500g/t, sodium cyanide 500~1000g/t, diesel oil 100~300g/t.
