What technologies are used in gold processing?

At DasenMining, we have meticulously analyzed a wide range of gold ores and developed specialized processing schemes that optimize recovery rates while minimizing costs. Our comprehensive approach ensures that no gold is left behind, regardless of the ore’s complexity.

Our company has summarized a variety of gold processing schemes, which are mainly based on the different properties of gold ore, and the washing schemes employed are also different. Combined beneficiation is used to recover gold from some grade ores.

Tailored Solutions for Diverse Gold Ores
1. Coarse-grained gold in Quartz Veins and Oxidized Ores:
For ores with coarse-grained gold, such as those found in quartz vein deposits and oxidized ores, we employ a single mercury mixing process. This method effectively captures coarse gold particles, providing a straightforward and cost-effective solution.

2. Quartz Vein Gold Bearing Ore:
When dealing with quartz vein gold-bearing ore, we utilize a combined washing process that integrates mercury mixing and gravity separation. This dual approach enhances the recovery of gold by leveraging the strengths of both methods.

3. Gold Bearing Oxidized Quartz Vein Ore:
For this type of ore, we apply a combined method of gravity separation (mercury mixing) – cyanidation. This process is particularly effective in recovering gold from oxidized quartz veins, ensuring high recovery rates.

4. Sulfide Gold Bearing Quartz Vein Ore, Polymetallic Gold Bearing Sulfide Ore, and Carbon (Graphite) Ore:
These ores, characterized by fine gold particles and high floatability, are processed using a single flotation washing process. This method is ideal for ores where gold is closely associated with sulfides and other floatable minerals.

5. Oxidized Ore with Free Gold and Single Flotation Treated Ore:
We employ mercury mixing flotation for these ores, which effectively recovers gold that is free or loosely associated with other minerals.

6. Fine or Fine Particle Dispersion of Gold in Quartz Vein Ore:
Despite deep oxidation and the absence of certain elements like Cu, As, Sb, Bi, and carbonaceous substances, we utilize the whole slime cyanidation (direct cyanidation) separation and washing process. This method is highly effective in recovering fine gold particles.

7. Gold Bearing Quartz Vein Ore and Quartz Pyrite Ore with Close Symbiosis:
For ores where gold and sulfide have a close symbiotic relationship, we use the flotation concentrate cyanidation beneficiation process. This method is designed to handle floatable minerals that are harmful to cyanidation, ensuring maximum gold recovery.

8. Ore with Close Symbiosis Between Gold and Sulfide:
When gold can only be recovered by smelting, we employ a combined flotation gravity separation and washing process. This method is tailored for ores where traditional methods fall short.

9. Low-Grade Gold Ore:
For low-grade ores, we utilize the heap leaching beneficiation process, a type of cyanidation gold extraction method. This cost-effective solution is ideal for ores with low gold content.
