In Tajikistan, a new 2000-ton gold ore processing facility has been established. It features innovative design principles and environmentally sustainable production methods. The design of the facility was developed based on the ore's properties, experimental beneficiation results, and production practices from similar mines. Its advanced processing technology ensures efficient resource development while protecting the ecological environment.
The ore is mainly composed of quartz carbonate breccia oxide and skarn oxide. Contains valuable elements such as gold, silver, copper, etc. Through multi-element chemical analysis and phase analysis of the original ore. The design team has determined the distribution characteristics of elements such as gold, copper, and arsenic in the ore. Provided scientific basis for subsequent process design.
In terms of crushing and grinding technology, the beneficiation plant adopts a process flow of coarse crushing+semi autogenous grinding+ball milling+hard rock return. The selection of this process is based on the properties of the ore and the production practices of similar mines both domestically and internationally, with the aim of simplifying the process flow, reducing operational steps, improving processing capacity, and reducing production costs. The application of semi autogenous grinding and ball milling technology not only reduces the number of equipment and factory floor space, but also improves the flexibility and environmental friendliness of operations.
The carbon leaching process is one of the core processes of the beneficiation plant, which achieves simultaneous leaching and adsorption of gold by adding activated carbon to the slurry. The adoption of this process not only reduces the number of leaching tanks and shortens the process, but also improves the dissolution kinetics conditions of gold and increases the leaching rate of gold. The application of carbon leaching technology reflects the innovative thinking of mineral processing plants in improving production efficiency and reducing production costs.
The countercurrent washing process plays an important role in hydrometallurgy, as it involves washing the leached slurry to recover useful components from the bottom stream of the thickener. The beneficiation plant adopts a three-stage countercurrent washing process, which optimizes the washing process and selects efficient thickeners to achieve efficient recovery of useful components and smaller discharge of wastewater.
The smelting process is the final stage of the beneficiation plant's process flow. It uses a high-temperature and high-pressure cyanide free desorption electrolysis device to desorb and electrodeposit the gold in the gold loaded carbon to obtain crude gold mud. Then, through processes such as wet method, pyrometallurgy, and solvent extraction, high-purity gold ingots are finally obtained. The application of this process not only improves the gold recovery rate, but also reduces production costs and enhances economic benefits.
In terms of tailings disposal, the beneficiation plant adopts the method of tailings pond storage, which achieves safe storage of tailings through uniform multi-point discharge in front of the dam and artificial tailings stacking of sub dams. At the same time, the beneficiation plant has also taken a series of energy-saving measures, such as large-scale equipment specifications, variable frequency control of grinding machines and other equipment, and the use of efficient grading equipment, effectively reducing energy consumption and production costs.
The design feature of this beneficiation plant lies in the selection of new and large-scale equipment, the use of semi autogenous grinding+ball milling process, the application of high-temperature and high-pressure cyanide free desorption electrolysis device, and the use of pre plant return water system and tailings pond return water system in the tailings facilities. These designs not only improve production efficiency and reduce production costs, but also reflect the responsibility and commitment of the beneficiation plant in environmental protection.
This 2000 ton gold ore beneficiation plant has advanced process design and environmentally friendly production methods. It not only achieves efficient development of resources, but also demonstrates the positive attitude and innovative ability of mining enterprises in environmental protection.
