Challenges and Solutions in Mineral Flotation Dispersants by Chemi Tech

In mineral flotation operations, common challenges such as slime coating, incomplete separation of valuable minerals from gangue, and high reagent consumption are prevalent. These issues directly lead to fluctuations in concentrate grade and difficulties in improving metal recovery, severely constraining the economic benefits of processing plants. Achieving efficient dispersion of the pulp system has become a key factor in enhancing flotation efficiency.

Chemi Tech has deep expertise in the mineral processing field and a thorough understanding of these challenges. We provide not generic reagents, but a series of high-efficiency dispersants developed specifically for different ore characteristics (such as silicate, carbonate, metal oxide gangue, etc.). Our solutions aim to effectively disperse fine slimes through physicochemical actions, preventing them from coating the surfaces of target minerals. This significantly improves the floatability of valuable minerals and promotes highly selective separation from gangue.

Our professional solution follows a clear four-step process:

Step 1: Diagnostic Analysis. Our technical team conducts a detailed evaluation of your ore sample, analyzing slime composition, particle size distribution, and pulp chemistry to accurately identify the root cause of the dispersion problem.

Step 2: Customized Formulation. Based on the diagnosis, we select or blend a specialized dispersant from the Chemi Tech product library that best suits your ore's characteristics, ensuring targeted and optimal performance.

Step 3: On-site Adjustment. We provide detailed recommendations for addition points, dosage, and concentration control, and can conduct industrial trials on-site to ensure seamless integration with your existing process flow for maximum effectiveness.

Step 4: Continuous Optimization. We establish a long-term monitoring mechanism to fine-tune the solution based on production data, ensuring stable and efficient operation.

Case Study: A metal ore processing plant was persistently troubled by interference from fine-grained silicate slime, resulting in concentrate grade consistently below design targets and high collector consumption. After implementing a customized Chemi Tech silicate dispersant, while maintaining the same throughput, the pulp dispersion improved markedly, and the froth layer became cleaner. Ultimately, the plant achieved an increase of approximately 1.8 percentage points in concentrate grade and a reduction of about 15% in the unit consumption of the key collector, realizing dual optimization of grade and cost.

Facing complex mineral processing environments, choosing a professional dispersant partner is crucial.
