Embodiment 1

[0019] The first example of the flotation enrichment method of zinc silicate ore of the present invention comprises the steps:

[0020] 1. Mineral raw materials:

[0021] The zinc content in the ore used is 8.78%, and the silicon content is 15.61%. Phase analysis shows that zinc mainly exists in the form of zinc silicate ore, and gangue minerals mainly exist in the form of carbonate and silica minerals.

[0022] 2. Flotation agents and operating conditions:

[0023]

[0024] During the flotation process, add sodium hexametaphosphate and tannin extract to the ore mill to grind the ore until the mineral monomers are dissociated, then use sodium hydroxide to adjust the pH value of the pulp to 10-11, and then add lauryl sulfuric acid Sodium and dodecylmercaptan are used for flotation, and the flotation foam is zinc silicate concentrate. According to the above medicament parameters, one roughing, four times sweeping and three times beneficiation were used to carry out the test...

Abstract

The invention discloses a flotation enriching method for willemite. According to the method, sodium hexametaphosphate and tannin extract are taken as gangue mineral inhibitors, lime and salicylaldoxime are taken as willemite activating agents, and lauryl sodium sulfate and lauryl mercaptan are taken as willemite collecting agents. Due to the adoption of the flotation enriching method, willemite minerals can be effectively floated and enriched. After one time of rougher flotation, four times of scavenging and three times of concentration are performed under the condition that the feed zinc content is 8.78-15.66 percent, zinc silicate concentrate of which the zinc content is 45.67-46.74 percent and the recovery rate is 83.15-85.61 percent is obtained.

Description

1. Technical field [0001] The invention relates to a flotation enrichment method for oxidized minerals, in particular to a flotation enrichment method for zinc silicate ore. 2. Background technology [0002] In the flotation enrichment process of zinc silicate ore, because the buoyancy of zinc silicate ore is close to that of impurity minerals such as calcium carbonate, quartz, etc., and because impurity minerals are easy to form slime in the process of crushing and grinding It affects the flotation performance of zinc silicate ore, making it difficult to flotation and enrich zinc silicate minerals; The low flotation index limits the development and utilization of zinc silicate ore. 3. Contents of the invention [0003] The object of the present invention is to provide a flotation enrichment method for zinc silicate ore, which can recycle zinc silicate ore, so that zinc silicate ore can obtain higher grade and recovery rate. [0004] The present invention adopts the foll...
