Problems solved by technology

[0002] At present, most of the agents added in the beneficiation of silver-zinc mixed ore are black medicine, xanthate, lime, copper sulfate, A9, T9, sodium sulfide and other agents. Due to the variety of agents added, the addition of agents is more troublesome, and the loss of agents cannot be effectively controlled. The dosage, the dosage of the agent is relatively large. The dosage of the agent required to extract the silver-zinc component per 1000 kilograms of raw ore reaches 0.18-0.20 kilograms, which increases the cost of the agent and increases the cost of the beneficiation process, and the recovery rate of the silver-zinc content in the raw ore is very low. , the recovery rate of silver and zinc content is less than 50%, resulting in low resource utilization

Embodiment 1

[0010] The agent improvement method in the flotation process of silver-zinc mixed ore, the agent improvement method uses butylamine black drug to replace the black drug, xanthate, lime, copper sulfate, A9, T9, sodium sulfide and other agents added in the ore dressing. Add 0.06 kg of butylamine black drug per 1000 kg of pulp during the beneficiation process, and add 0.04 kg of butylamine black drug per 1000 kg of pulp during the sweeping process.

Embodiment 2

[0012] The agent improvement method in the flotation process of silver-zinc mixed ore, the agent improvement method uses butylamine black drug to replace the black drug, xanthate, lime, copper sulfate, A9, T9, sodium sulfide and other agents added in the ore dressing. Add 0.069 kg of butylamine black drug per 1000 kg of ore pulp during the beneficiation process, and add 0.046 kg of butylamine black drug per 1000 kg of ore pulp during the sweeping process.

Embodiment 3

[0014] The agent improvement method in the flotation process of silver-zinc mixed ore, the agent improvement method uses butylamine black drug to replace the black drug, xanthate, lime, copper sulfate, A9, T9, sodium sulfide and other agents added in the ore dressing. Add 0.075 kg of butylamine black drug per 1000 kg of ore pulp during the beneficiation process, and add 0.050 kg of butylamine black drug per 1000 kg of ore pulp during the sweeping process.

[0015] In the above-mentioned examples 1-3, the consumption ratio of adding butylamine black drug per 1000 kg of ore pulp in the roughing process is guaranteed to be 3:2, and the whole silver-zinc mixture In the ore flotation process, the total amount of chemicals per 1000 kg of raw ore is 0.100-0.125 kg.

Abstract

The invention relates to an agent improvement method used in the silver and zinc compound ore flotation process. Ammonium dibutyl dithiophosphate is adopted for replacing agents such as black catching agents, xanthate, lime, copper sulfate, A9, T9 and sodium sulphide which are added during flotation. The improvement method includes the following steps that firstly, cracked raw ore is added into a flotation mixing tank and subjected to roughing, 0.06 kg-0.075 kg of the ammonium dibutyl dithiophosphate is added to per 1000 kg of ore pulp in the roughing process, chemical reactions occur after the ammonium dibutyl dithiophosphate is added, and roughing concentrate is extracted; secondly, the roughing concentrate is discharged into a flotation tank and subjected to scavenging, 0.04 kg-0.005 kg of the ammonium dibutyl dithiophosphate is added to per 1000 kg of ore pulp in the scavenging process, chemical reactions occur after the ammonium dibutyl dithiophosphate is added, and silver and zinc components in the roughing concentrate are further extracted. According to the agent improvement method used in the silver and zinc compound ore flotation process, the recovery rate of silver and zinc in the raw ore is increased and is higher than 50%, the use quantity of agents is reduced, agent cost is reduced by about 30 yuan per ton of the raw ore, and flotation cost is reduced.

Description

technical field [0001] The invention relates to a beneficiation method, in particular to a method for improving reagents in the flotation process of silver-zinc mixed ore. Background technique [0002] At present, most of the agents added in the beneficiation of silver-zinc mixed ore are black medicine, xanthate, lime, copper sulfate, A9, T9, sodium sulfide and other agents. Due to the variety of agents added, the addition of agents is more troublesome, and the loss of agents cannot be effectively controlled. The dosage, the dosage of the agent is relatively large, the dosage of the agent required to extract the silver-zinc component per 1000 kg of raw ore reaches 0.18-0.20 kg, which increases the cost of the agent and increases the cost of the beneficiation process, and the recovery rate of silver-zinc content in the raw ore is very low , the recovery rate of silver and zinc content is less than 50%, resulting in low resource utilization.
