The jaw crusher is the preferred choice for processing hard rock gold ores.Jaw crusher with larger feed openings and bigger crushing strokes, it is suitable for crushing big size lumps in large quantity.From the welded steel base to the rugged eccentric shaft, the jaw crusher is built with brute strength with quality bearings. Jaw crusher is one of the main types of secondary crushers in a mine or ore processing plant. Its high-strength structure and efficient crushing capacity make it a core component of gold ore pre-processing. This equipment features a “V”-shaped crushing chamber design, allowing precise control of crushed particle size by adjusting the discharge opening.
Crushed/ground ore is graded by particle size using multiple screens. Screening equipment plays a key role in the rock gold processing process and is an essential step, directly impacting beneficiation efficiency and recovery rates. It is widely used in pre-processing to remove waste rock, grade ore before grinding, and grade concentrates/tailings after separation.
Ball mills achieve deep disaggregation of rock gold ore through the impact and grinding of steel balls. Ball mill is an efficient tool for grinding many materials into fine powder, it is widely used in building material, and chemical industry,can be divided into tabular type and flowing type according to different expelling mine ,There are two ways of grinding: the dry way and the wet way. They are categorized by discharge method: grate-type mills are suitable for coarse grinding, producing a product size of 200-325 mesh; overflow-type mills are suitable for fine grinding, achieving a particle size of up to 400 mesh. Their linings are made of high-chromium cast iron to resist abrasion from hard ore.
Wet pan mills feature an integrated “grinding + compaction” design, making them particularly suitable for small gold mines with a daily processing capacity of less than 50 tons. wet pan mill 1200 is the best equipment to replace ball mill. because it have small investment, high output, low production cost, good efficiency and easy installation.Consisting of a cast iron platen and two to three rollers, the equipment wet-grinds the ore through rotation and revolution, achieving a product fineness of 150-200 mesh. Gravity settling is also used to initially separate free gold. Amalgam can also be added to concentrate gold particles. While this method offers low investment costs, it’s important to note that it’s more effective at recovering gold particles larger than 0.5mm. Fine gold particles require gravity separation equipment.
Slurry classification is achieved primarily through the synergistic effect of gravity settling and spiral conveying. Within the inclined trough, the ground slurry is driven by water flow, causing fine particles to overflow from the upper portion of the trough. Coarse particles (sand) are conveyed upward by spiral blades to the discharge outlet, where they return to the ball mill for further grinding, forming a closed “grinding-classification” cycle. This classifier is particularly suitable for processing rock gold ores with high mud content and unevenly distributed gold particles.
