Custom Leaching Tank Manufacturers China

1.Product Introduction Gold Ore Processing Equipment

Custom Leaching Tank Manufacturers China is a piece of metallurgical equipment designed for liquid-solid reactions under atmospheric pressure and temperatures below 373K (C). It is widely utilized in the hydrometallurgy of non-ferrous metals, such as gold, zinc, and nickel. The core function of this equipment is to ensure thorough contact between the ore slurry and the leaching agent through agitation, thereby achieving the dissolution and extraction of the target metals.

2.Application Gold Ore Processing Equipment

Custom Leaching Tank Manufacturers China applications are extensive, primarily covering the following fields:

• Gold Smelting and Extraction:In the cyanidation process, leaching tanks—particularly air-agitated models like the Pachuca tank—are used to dissolve gold from ore. Optimized air-agitated tanks can increase the gold leaching rate by approximately 0.8% by significantly improving the dissolved oxygen (DO)levels in the slurry.
• Zinc Smelting:The vertical mechanical agitation tank is the most widely used equipment in zinc hydrometallurgy. Specifically designed for leaching zinc calcine (roasted ore), this equipment has reached standardized industrial production levels.
• Nickel and Other Non-ferrous Metals:Leaching tanks are also essential in the hydrometallurgical processing of nickel and copper. They utilize acidic or alkaline solutions to selectively dissolve target metals from the ore or concentrate.
• Cyanide Leaching of Uranium, Gold, and Silver:Combined agitation tanks (such as the Dorr-type agitator) are suitable for leaching processes that require oxygen supply, such as the cyanide leaching of uranium, gold, and silver ores. These structures can be integrated with heating systems to further enhance reaction efficiency.

3.Working Principle

The leaching tank is a critical piece of equipment in mineral processing and hydrometallurgy used for metal extraction. Its core function is to dissolve valuable metals from ore into a solution using chemical solvents, facilitating subsequent recovery. Based on their structure and agitation methods, these tanks are primarily categorized into two types: mechanical agitation and air-agitated (pneumatic) tanks. While their specific operating principles differ slightly, the overall process flow remains consistent.

4.Advantages

• High Recovery for Fine Gold: It can achieve recovery rates exceeding 95% for 0.04mm free gold and over 99% for alluvial gold.

• Automation: Modern models support continuous discharge and fully automated operation, significantly boosting production efficiency.

• Eco-Friendly: With an enrichment ratio of 1,000–3,000 times, it achieves high concentration without the use of chemical reagents.

• Versatility: It handles feed concentrations from 2% to 50% and is highly effective for processing high-slime materials.

• Enhanced Extraction Rates: Through mechanical agitation, aeration, or counter-current contact, it ensures thorough interaction between materials and leaching agents (e.g., acid or cyanide), maximizing recovery.

• Process Adaptability: Parameters such as agitation speed, temperature, and acid concentration can be precisely adjusted to handle various ore grades and particle sizes.

• Energy and Cost Efficiency: Modern designs, such as those used in High-Pressure Acid Leaching (HPAL), incorporate heat recovery systems and automated level controls to reduce energy consumption and labor costs.

• Industrial Scale: Its compact and continuous-flow design supports stable, large-scale industrial production, meeting the high-capacity demands of modern mining.
