Abstract

The invention relates to a multi-air-stream pulse injection-type floatation machine for floatation of multi-metal sulfide mineral poor in tin. The multi-air-stream pulse injection-type floatation machine is characterized by comprising a groove body (11), a main shaft (5), a stirring impellor (9), a stator mechanism (10), a foaming scraping plate (8) and a multi-air-stream pulse air inflating system; the multi-air-stream pulse air inflating system comprises a high-speed electro-hydraulic servo reversing valve (2), unidirectional air intake valves (13) and a false base (14); the unidirectional air intake valves (13) are installed on the false base (14), and are communicated with an inner cavity of the false base (14); and the number distribution characteristic of the unidirectional air intake valves (13) is that the number of the unidirectional air intake valves (13) under the stator mechanism (10) accounts for 65%-80% of the total number. Compared with the prior art, the multi-air-stream pulse injection-type floatation machine has the advantages that gases and ore pulp are mixed much effectively; not only is gas absorption amount great, but also the bubble distribution is uniform; and moreover, the integral machine has high automation degree, and has a favorable floatation effect.

Description

technical field

[0001] The invention relates to the technical field of mineral processing equipment, in particular to a multi-flow pulse injection type flotation machine. Background technique

[0002] The Dachang mining area is a cassiterite polymetallic sulfide ore, and there are many kinds of useful minerals in the ore. The main minerals are cassiterite, sphalerite, brittle pyrotite, pyrite, pyrrhotite, arsenopyrite and a small amount of arsenopyrite. Lead ore, sphalerite, chalcopyrite, zurtzite. Gangue minerals are mainly quartz and calcite. The elements with industrial value in ore are tin, lead, antimony, zinc, sulfur, arsenic and associated rare and precious elements indium, cadmium, gallium, gold and silver. The rich ore resources in the mining area have been gradually exhausted after decades of mining, and the ore processed at present is mainly lean ore, and the grade is declining year by year. Among them, the fire-burned tin polymetallic lean ore is an important ...
