Gold Tailings Comprehensive Utilization: Solutions for Environmental Protection and Industry Sustainability | Zhengzhou Jinquan
Gold tailings are solid wastes from gold ore beneficiation. As a by-product of gold mining, they contain residual minerals, fine particles and trace elements. Importantly, improper treatment of these tailings will pose significant challenges to the environment and land resources.
Risks of Unregulated Gold Tailings Handling
Unregulated stacking of gold tailings wastes large areas of valuable land. Besides, it also creates potential environmental risks. For example, fine tailing particles easily produce dust. Additionally, natural weathering can leach residual cyanide, heavy metals and other harmful substances into soil and groundwater.
As a result, this leaching causes long-term ecological pollution and threatens the health of surrounding organisms.
Challenges Facing the Global Gold Industry
The international gold market is constantly changing, and this brings unprecedented challenges to the global gold industry. Specifically, these challenges include fluctuating gold prices, stricter environmental requirements and resource conservation pressure.
As a major global gold producer and consumer, China’s gold industry is working hard to achieve green and sustainable development while improving production efficiency.
The Importance of Gold Tailings Comprehensive Utilization
Against this backdrop, gold mining enterprises must upgrade their mining and beneficiation technologies. Moreover, they also need to strengthen the research and application of gold tailings comprehensive utilization processes.
In fact, this is an inevitable choice to promote high-quality development of the gold industry. For instance, effective tailings utilization reduces environmental pollution and land occupation.
Furthermore, it also recovers valuable associated elements such as copper, silver and iron from tailings, turning waste into treasure and boosting enterprise economic benefits.

Gold Tailings Gravity Separation Process Related Pictures & Annotations
1. Nelson Centrifugal Concentrator (Core Equipment for Coarse Gold Gravity Separation from Gold Tailings) — It is often used to intensify the recovery of fine and coarse free gold from gold tailings. As a key enrichment equipment in the gold tailings gravity separation process, it is mostly combined with shaking tables to form a joint process, which effectively improves the recovery rate of gold in tailings.
2. Double-Layer Shaking Table (Concentrating and Scavenging Equipment for Tailings Gravity Separation) — It performs secondary enrichment on the Nelson concentrate or the ore flow after tailings classification, which can effectively separate gangue from gold particles and further improve the gravity separation recovery rate, supporting the gold tailings comprehensive utilization.
3. Hydrocyclone + Thickener (Classification and Dehydration Unit Before Tailings Gravity Separation) — As a pre-process of gold tailings gravity separation, it is used for pulp classification and concentration dehydration to ensure that the pulp concentration and particle size entering the gravity separation equipment meet the process requirements, laying a foundation for efficient gravity separation.
4. Gold Tailings Gravity Separation Workshop Production Line (Overall Process Scene) — It includes a complete assembly line of grinding, classification, centrifugal gravity separation and shaking table concentration, which fully demonstrates our company’s overall solution capability for the gold tailings gravity separation process.
5. Subsequent Recovery/Filling System for Gravity Separated Tailings (Process Closed-Loop Link) — The tailings after gravity separation are further dehydrated and associated elements are recovered, or used for underground goaf filling, which is consistent with the theme of "gold tailings comprehensive utilization" in the article and realizes the green recycling of tailings resources.
