Embodiment 1

[0040] Mix 150g of hydrocarbyl dithiophosphoric acid sulfide ester, 100g of 1,2-tetradecyl dithiol, and 100g of N,N-diethyl-2-mercaptobenzenesulfenamide, and use a beaker as a container at normal temperature and pressure. Stir with a magnetic stirrer for 30-40 minutes to obtain collector LP-12.

Embodiment 2

[0042] Mix 250g of hydrocarbyl dithiophosphoric acid sulfide ester, 100g of 1,2-tetradecyl dithiol, and 100g of N,N-diethyl-2-mercaptobenzenesulfenamide, and use a beaker as a container under normal temperature and pressure. Stir with a magnetic stirrer for 30-40 minutes to obtain collector LP-12.

Embodiment 3

[0044] Mix 200g of hydrocarbyl dithiophosphoric acid sulfide ester, 100g of 1,2-tetradecyl dithiol, and 100g of N,N-diethyl-2-mercaptobenzenesulfenamide, and use a beaker as a container at normal temperature and pressure. Stir with a magnetic stirrer for 30-40 minutes to obtain collector LP-12.

Abstract

The invention provides an ore dressing method for lead-zinc-silver poly-metallic ores. Lead-silver concentrates and zinc concentrates are finally obtained through the steps of raw ore grinding, lead fast roughing, lead slow roughing, lead scavenging, lead fast concentration, lead slow concentration, zinc fast roughing, zinc slow roughing, zinc scavenging, zinc fast concentration and zinc slow concentration. The lead-zinc-silver poly-metallic ores sorted by the ore dressing method provided by the invention are good in sorting index and high in separation efficiency; the ore dressing method is a lead-zinc-silver ore dressing method which is stable, efficient, strong in adaptive capacity, good in sorting 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 mineral processing field, in particular to a mineral processing method of lead-zinc-silver polymetallic ore. Background technique [0002] my country is a country with a large amount of lead and zinc resources. Its resource reserves, output, consumption and export volume are all in the forefront of the world. It has an important influence in the world and occupies an extremely important position. However, in recent years, with the vigorous mining of mineral resources, the lead-zinc resources that are easy to select, high-grade, and single-species are continuously decreasing, and a large number of lead-zinc ores that are difficult to select and polymetallic continue to increase, and such resources generally contain lead-zinc main metals. Low grade and high sulfur content, good buoyancy of sulfur iron minerals and difficult to suppress, uneven particle size of lead-zinc minerals, poor monomer dissociation, high content of asso...
