Mining & Industrial Energy Solutions

1.Industry Pain Points & Challenges

In gold mining (especially placer gold mining and sluice box beneficiation), mine owners often face the following losses:

(1) Significant loss of fine-grained gold: Traditional sluice boxes or inferior bedding materials cannot effectively intercept tiny fine-grained gold particles, resulting in significant loss along with the tailings and direct profit losses.

(2) Rapid wear and tear on gravity separation equipment: Ore sand has extremely strong abrasive properties; ordinary carpets or mats are easily worn down by sludge and require frequent shutdowns for replacement.

(3) Difficulty in cleaning and recycling: Some gold-catching mats have unreasonable structural designs, making it difficult to thoroughly clean the gold powder adhering to them, resulting in secondary waste.

-Damage to heavily loaded road surfaces in mining areas: Ore trucks cause unstable roadbeds, affecting the overall production rhythm.

2.System Solution Changfeng offers a professional combination of “High-Efficiency Gold Extraction + Mine Area Reinforcement”:

(1) High-Efficiency Sluice Box Gold Extraction System: Utilizes professional gold-finding carpet. Its unique fiber structure forms micro-vortices, using gravity differences to firmly lock in heavy metal particles (such as gold), effectively preventing fine gold from escaping.

(2) Heavy-Duty Road Reinforcement in the Mine Area: Uses high-strength geogrids to enhance the shear strength of the ore transport roadbed, ensuring unimpeded passage for heavy engineering machinery.

(3) Heap Leaching Site Safety and Seepage Prevention: Lays a high-thickness HDPE geomembrane in the heap leaching area to ensure 100% collection of precious solutions containing cyanide.

(4) Foundation Layer Stabilization and Constraint: Utilizes geocells to provide three-dimensional constraint on the soft foundation of the mine area, improving the overall modulus of the foundation.

3. Core Advantages

(1) Significantly Increased Recovery Rate by 20%-30%: Changfeng Gold-Pulling Grass’s special “gold-catching” fiber design can capture micron-sized fine gold that ordinary materials cannot intercept, directly increasing mine profits.

(2) Excellent Abrasion Resistance and Flexibility: Designed for ore sand scouring environments, it has an extremely long service life, reducing downtime for parts replacement.

(3) Easy Cleaning and High Output: The fiber structure is specially treated, allowing for complete unloading of gold powder with simple rinsing during cleaning, making the recovery process more efficient.

(4) All-Terrain Adaptability: Whether used in large gold dredges, sluices, or river hand sorting, it exhibits excellent gravity capture performance.
