In the fields of gold beneficiation and alluvial gold recovery, gold panning grass is widely used as a physical beneficiation auxiliary material due to its simple operation and controllable costs. Shandong Kaina, an enterprise engaged in wholesale and retail businesses covering automotive supplies, home furnishings, crafts, and hardware and electrical machinery, offers gold panning grass as a supporting material for mineral processing equipment within its product line.
In industrial applications, gold panning grass is commonly referred to as gold-adhesive grass, gold-absorbing grass, or gold recovery mat. It is not a natural plant but rather a functional material made from high-strength plastics such as polyethylene (PE). The gold panning grass products provided by Shandong Kaina feature a surface design of dense, grass-like textured fibers, with fiber heights typically ranging from 20mm to 30mm across various specifications. This structural design leverages the dual effects of gravitational settling and fiber adsorption. When mineral sand and water containing gold particles flow over the material's surface, the heavier gold particles are trapped within the fiber layer, while lighter silt and sand are discharged with the water flow, thereby achieving preliminary enrichment and separation of minerals.
In practical operations, gold panning grass is mainly applied in the recovery processes of alluvial gold, rock gold, and gold tailings. According to standard operating procedures, the material is cut to fit the width of the sluice box, generally laid out in lengths of 4 to 10 meters, and fixed at the bottom of the sluice. Shandong Kaina's gold panning grass products are designed for use in conjunction with equipment such as trommel screens and vibrating screens, making them suitable for various working conditions including gold dredging vessels, large-scale gold recovery beds, and flow sluices.
Regarding maintenance, the material boasts a long cycle service life due to its corrosion-resistant and wear-resistant plastic composition. Operators typically perform regular cleaning based on the gold content of the ore feed. The material can be removed, shaken, and rinsed for repeated use without the need for complex chemical reagents, aligning with the environmental requirements of green mining operations.
Currently, gold panning grass products on the market are categorized into different types based on fiber morphology, including upright filament, crimped filament, and brushed绒 (flocked) types, to meet the capture needs of coarse gold, fine gold, or mixed ore materials. As a trading enterprise, Shandong Kaina aims to meet the needs of mineral processing operations of varying scales through its product offerings. For river channels with rapid water flow or roughing stages, upright filament products with greater fiber height and strong resistance to fast currents are typically selected. Conversely, for tailing scavenging or fine gold recovery, fine-flocked materials with higher density are preferred. By providing a diverse range of specifications, these products effectively assist beneficiation enterprises in improving recovery efficiency and reducing operational costs.
