In the fields of mining and placer gold extraction, gold mining grass serves as a critical physical auxiliary material for mineral processing, and its performance directly impacts gold recovery efficiency. Relying on its wholesale and retail foundation, Shandong Kaina Trading Co., Ltd. provides standardized gold mining grass products to the market. Also known in the industry as gold-absorbing grass, gold-catching carpets, or gold mining mats, this artificial functional material is specifically designed for aquatic gold panning and mineral sand separation.
Regarding material and structure, the gold mining grass supplied by Shandong Kaina is primarily made of high-strength polyethylene (PE), with some products featuring an ethylene-vinyl acetate (EVA) anti-slip backing. This high-polymer composite material endows the grass with excellent wear resistance, corrosion resistance, and lightweight portability, allowing it to withstand the continuous scouring of mineral slurries and water-sand mixtures over the long term. In terms of specifications, the surface is covered with dense, rigid plastic grass fibers. Mainstream fiber height options range across 20mm, 22mm, 24mm, 26mm, and 30mm. Generally speaking, fiber height and density are the core indicators determining adsorption efficiency; taller fibers can create a more effective turbulent flow zone, thereby enhancing the capture rate of fine gold particles.
In practical application and working principles, this gold mining grass utilizes gravity separation based on the high specific gravity of gold. When mineral sand and water containing gold particles flow across the surface, the gold and other heavy minerals are trapped through the combined effects of gravity and fiber adsorption, while lightweight silt and mud are washed away with the water. For operation, users can cut the rolls (commonly 1 meter wide and 15 meters long) to fit the sluice box width and lay them down, working in conjunction with equipment like trommel screens or vibrating screens. Depending on the gold content in the slurry, the grass can be periodically removed, shaken, and rinsed to concentrate the gold sand and allow the material to be reused in a continuous cycle.
