There are usually 5 types of gold mines: placer gold ore, polymetallic gold ore, rock gold ore, iron oxide gold ore, gold-bearing sulfide gold ore, etc.

Gold mining equipment is mainly used to separate gold ore in the mineral processing industry. The methods for processing gold ore include flotation, magnetic separation and gravity separation.

Gold mining equipment: including jaw crusher, ball mill, classifier, flotation cell, dryer, gold shaker table, spiral concentrator, etc.

Gold Ore Processing Methods

1、Crushing and screening stage

Large pieces of gold ore need to go through processes such as coarse crushing and fine crushing to break into suitable particle sizes. The crushing process forms a closed loop. After being screened by the vibrating screen, materials that do not meet the requirements will be crushed twice until they meet the particle size requirements.

2、Grinding stage

Materials with a size of 0-25 mm are evenly sent to the ball mill for grinding, and are screened by a spiral classifier. Materials that do not meet the requirements are sent to the ball mill for continued grinding; they are ground into finer particles to prepare for the next step of beneficiation;

3、Ore Dressing Stage

At this stage, the specific mineral processing method isdetermined according to the material conditions. Core equipment at this stage: spiral chute, spiral classifier, shaker, flotation machine.

  • 1Gravity Separation of Gold Ore: The gravity separation process relies on the combined action of medium fluid and various mechanical forces to create a comfortable loose layer and separation conditions to obtain particles of different densities and sizes. Since the density of gold minerals is much greater than that of gangue minerals, a gravity separation process should be used for gold ores containing gold particles. The gravity separation method is only applicable to monomer dissociated gold ore (placer gold).

  • 2Flotation Separation of Gold Ore: First, feed the slurry into the flotation machine, add chemicals and stir thoroughly. While mixing, use air to attach the gold particles to the air bubbles. Bubbles floating on the surface are scraped off to separate gold particles and impurities. The process includes four parts: batching, stirring, aeration, and foam scraping.

4、Drying Stage

Send the obtained gold powder into a dryer to dry it to obtain gold fine powder.
