Gold sulfide (Au₂S) roasting method is a high-temperature oxidation treatment method. Through high-temperature roasting, the sulfur element in the gold sulfide is converted into gaseous sulfur dioxide (SO₂), and the gold is converted into an extractable oxidized state or metallic gold. This process is mainly used for the pre-smelting treatment of gold sulfide ore or gold-containing sulfides.
The rationality of mineral processing flowsheets directly impacts production efficiency and must be formulated based on ore testing, production practices, and practical conditions.
Gold extraction from carbon-in-leach (CIL) is an efficient gold extraction process that combines gold leaching with adsorption processes to reduce equipment and energy consumption and improve gold recovery.
Choosing the appropriate rotary kiln equipment requires careful consideration of various factors, including material type, production requirements, kiln design, equipment performance, and the manufacturer's reputation.
Jaw crusher is a key equipment in the ore coarse crushing process. It is widely used in various ores and rocks with a compressive strength not exceeding 320MPa with its excellent crushing capacity and high efficiency. However, in the actual production process, the jaw crusher may have uneven discharge particle size, affecting the crushing effect and subsequent process flow.
The world's major mineral producing countries is facing a severe environmental issue—massive tailings accumulation. Tailings are the waste materials left after valuable minerals are extracted from ores. Long-term storage of tailings not only occupies large areas of land but also leads to resource wastage, environmental pollution, and safety risks. However, tailings are not entirely worthless; they still contain valuable components that can be recovered. Proper treatment and comprehensive utilization of tailings are essential.
Sand washing machines are as the core equipment for cleaning sand and gravel aggregates, it is widely used in the purification of machine-made sand and natural sand. Through the dual effects of hydraulic impact and mechanical friction, it can effectively remove dirt, dust and other impurities attached to the surface of sand particles, while destroying the water vapor wrapping layer between sand particles, significantly improving the cleanliness and looseness of sand. In production, sand washing machines will inevitably encounter various problems.
Mobile stone crusher plant is divided into coarse crushing, medium crushing and fine crushing according to the size of feed and discharge particles in the crushing operation. It can be equipped with jaw crusher, impact crusher, cone crusher, sand making machine, hammer crusher and other equipment to meet the needs of the majority of users.
The following key issues should be noted in the daily use of a mobile tire crushing station to ensure efficient operation of the equipment, extend its life and ensure safety
Flotation equipment is a key equipment in the mineral processing process, and its operating status directly affects the mineral processing efficiency and product quality.
Sulfide gold ore usually refers to the type of ore associated with gold and sulfide (such as pyrite FeS₂, arsenopyrite FeAsS, etc.). Since gold is often present in sulfide in the form of fine particles or inclusions, direct cyanide leaching efficiency is low, so a specific beneficiation process is required for pretreatment and enrichment.
Flotation is the core technology for separation based on the differences in physical and chemical properties of mineral surfaces in mineral processing. The choice of its strategy directly affects resource utilization and economic benefits.
Ore dressing is an important process in mineral processing. Its purpose is to separate useful minerals from waste rocks in ore in order to obtain metal or non-metallic mineral products with higher purity.
In order to effectively extract metallic tin, mineral separation processes such as gravity separation, flotation and magnetic separation are required. These processes can accurately separate valuable tin minerals according to different ore characteristics, while removing impurities to ensure that the concentrate products meet the quality requirements of industrial production.
