The king of the industrial mining machines was the gold dredge. The dredge of wood and iron is a testament to engineering of the early 1900s. It is a huge boat floating in a manmade pond. Scooping up gravel in front, extracting gold on board, and dumping the gravel behind it.
2 Rockers. A rocker, also known as a cradle, separated gold from dirt. This tool consisted of a box for shaking dirt and water back and forth so miners could find gold fragments. A miner would load the rocker with water and soil. Another would rock the box, bucket
Process Introduction The flotation method is a widely used technique for the recovery of gold from goldcontaining copper ores, base metal ores, coppernickel ores, platinum group ores and many other ores where other processes are not applicable.
The gold mining equipment includes: jaw crusher, hammer crusher, roller crusher, impact crusher, vertical crusher, cone crusher, ball mill, vibrating screen, spiral separator, flotation machine, mining agitation tank, ore feeder, concentrator, mine hoist, mining conveyor belt, prewatering into a ball plate, spiral chute, beneficiation shaker, washing machine and other equipment.

Froth flotation is a process for selectively separating hydrophobic materials from is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Gold ore . Prominer maintains a team of senior gold processing engineers with expertise and global experience. These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and costefficient process designs.
The equipment used for surface alluvial mining was cheap, portable and easy to use. The pan and gold washing cradle were imported from California and used gravity to separate the gold (gold is heavier than water and the surrounding rock and soil). Together with the pick and shovel, this equipment provided adequate access to alluvial deposits.

Flotation is also used to remove impurities before hydrometallurgical treatment (ie, carbon preflotation) to purify lowsulfide and refractory ores for further processing. Flotation is considered to be the most costeffective method of concentrating refined gold and is often used in conjunction with flotation
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
