Description
Technical field
The utility model relates to zinc and smelts the device that reclaims gold and silver in acid leaching residue, and particularly a kind of zinc is smelted the device that gold and silver is reclaimed in the acid leaching residue flotation.
Background technology
Zinc hydrometallurgy is the topmost zinc metallurgy method in the world today, and its output accounts for more than 85% of the total zinc output in the world.The newly-built zinc production capacity with enlarging in the world all adopts Zinc hydrometallurgy process in the recent period.The Zinc Hydrometallurgy Technology technological process is: zinc concentrate directly leaches after roasting, reclaims zinc from immersion liquid, and ore pulp further reclaims zinc through concentrate drying by Rotary Kiln, and discharges leached mud, i.e. acid leaching residue.The gold that comprises in acid leaching residue and silver also all enter in acid leaching residue and are not recycled, and cause thus the precious resources waste.Contain the multiple valuable metals such as silver, gold, copper in acid leaching residue such as output in my company's zinc metallurgical process, its grade is Ag300-400g/t, Au1.5g/t, Cu0.6-1%.
The method that at present a lot of enterprises smelt acid leaching residue recovery gold and silver from zinc is floatation basically, and the equipment of employing is flotation device.Adopt the flotation device effect not satisfactory.
The flotation column existing application in many mines at home and abroad, and effect is better, but the producer of all uses all adopts flotation column and flotation device proportioning to use, and flotation column is generally as scanning, and the acid leaching residue of zinc smelting does not simultaneously also adopt the precedent of flotation column in processing.
Flotation column is that compressed air is seen through the pneumatic flotation cell that porous media (aerator) is inflated and stirred ore pulp.In flotation column when work,, the ore pulp that is in harmonious proportion through medicament is fed by the mine-feeding equipment of cylinder middle and upper part; Compressed air is through input pipe network and bellows chamber, then seeing through porous media (as the cellular plastic short tube) blasts bottom cylinder, make and form a large amount of tiny bubbles in cylinder, ore particle slowly descends under Action of Gravity Field, bubble passes the ore pulp that flows downward and rises floating, ore particle and bubble are realized the selective mineralising of bubble by counter current contacting and collision.Mineral laden bubble rises to assemble floating to the ore deposit liquid level and forms froth bed, gets froth pulp after overflowing and is concentrate; Mine tailing is by discharging by lifting device at the bottom of post.Be called selected district from ore pulp to entrance to capital in cylinder, Main Function is the grade that improves froth pulp; Be called at the bottom of the post to entrance by ore pulp and capture the district, Main Function is to capture the purpose mineral of wanting emersion, improves the rate of recovery.Aerator is the key component of flotation column, and its effect is for floatation process provides enough blast and air quantity, causes the bubble that is suitable in a large number flotation.
Blast, air quantity are two essential conditions in the flotation column operation.Generally, the flotation column Air Quantity Required is 1.5～2.5 meters
3/ rice
2Minute, blast is 0.8～1.5 kilogram/cm
2Sort coarse grain, greatly than heavy mineral, when pulp density was higher again, airflow pressure is the capping value all.And fine, low concentration ore pulp Air Quantity Required blast can cut down according to the circumstance.The raw meal particle size scope that flotation column is suitable for processing is between 0.074～0.015 millimeter, and flotation column itself does not have power set and accessory, and only its corollary equipment compressor needs power.Flotation column optimum fine particle mineral flotation in a word, and acid leaching residue belongs to fine-particle minerals just at the right time.
