The process flow of lead-zinc ore treatment can be divided into the following steps:
Ore pretreatment: Screening, crushing, magnetic separation and other pretreatments are carried out on the lead-zinc ore to remove large ore, gangue and impurities.
Flotation: Use flotation machines to separate gangue, impurities and graphite in lead-zinc ore. Specific operations include dosing flotation, shaking table flotation, etc., to obtain roughed lead-zinc concentrate.
Rough separation: use shaking table and other equipment to re-select lead-zinc concentrate to obtain more pure lead-zinc products.
Selection: Use equipment such as selection machines to select lead-zinc products to obtain higher-quality lead-zinc products.
Smelting: Add lead and zinc products into a high-temperature furnace to smelt them into lead and zinc ingots.
Processing: Cutting, grinding, surface treatment and other processing of lead-zinc ingots to make various lead-zinc products.
The above are the main steps of the lead-zinc ore treatment process, and the specific operations may vary with different lead-zinc ore types and processing techniques. In actual production, each step should be optimized and adjusted according to specific conditions to obtain higher quality lead-zinc products.
