[0036] Mix 40g of diiodomethane, 96g of thallium malonate, 43g of tetrabromoethane, and 275g of pyrrhotite powder (Fe content 59.1%, S content 36.8%, magnetic mineral content 96.4%), and make it in a beaker under normal temperature and pressure. The container and a magnetic stirrer were stirred for 90 minutes to obtain the separation reagent ZS-01.

Embodiment 3

[0038] Mix 220g of sodium N,N-diethyldithiocarbamate, 100g of hydrocarbyl dithiophosphoric acid sulfide ester, and 130g of 1,2-tetradecyldithiol, and use a beaker as a container under normal temperature and pressure, and magnetically stir and stirred for 30 minutes to obtain collector LP-13.

[0039]Mix 40g of diiodomethane, 85g of thallium malonate, 60g of tetrabromoethane, and 300g of pyrrhotite powder (Fe content 57.5%, S content 36.7%, magnetic mineral content 96.8%), and make it in a beaker under normal temperature and pressure. The container and a magnetic stirrer were stirred for 75 minutes to obtain the separation reagent ZS-01.

Abstract

The invention provides a beneficiation method for lead-zinc separation of refractory lead-zinc ore. The beneficiation method comprises the steps of raw ore levigation, mixing rough separation, scavenging, mixing fine separation, filtration dehydration, lead-zinc separation and magnetic separation, and lead-silver ore concentrate and zinc ore concentrate are obtained finally. The lead-zinc ore separated by the beneficiation method is good in separation index, high in separation efficiency and low in production cost, and the beneficiation method for the lead-zinc separation of the refractory lead-zinc ore is simple and efficient, is high in adaptability, good in separation effect, high in comprehensive recovery index, and low in production cost, and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of mineral processing, in particular to a mineral processing method for separating lead and zinc from refractory lead-zinc ores. Background technique [0002] my country is rich in lead and zinc resources, ranking among the top in the world. However, unlike other countries in the world, our country has vigorously exploited mineral resources in recent years, and the easy-to-select high-grade lead-zinc ores have been continuously reduced, resulting in a large number of difficult-to-select low-grade lead-zinc ores. The ore is constantly increasing, and such resources generally have the characteristics of low lead-zinc main metal grade and high sulfur content, uneven particle size distribution of lead-zinc minerals, poor monomer dissociation, and certain oxidized mud content in the ore. These factors affect And led to the low overall utilization rate of lead-zinc mineral resources in my country, and the comprehensive recove...
