YX500ST: A High-Efficiency and Eco-Friendly Gold Leaching Reagent - The Ultimate NaCN Replacement

Product Description

D486 is a specialized carbon depressant independently developed by Y&X Beijing Technology Co., Ltd. This innovative product is engineered to inhibit fine carbonaceous minerals, including graphite, organic carbon, and free carbon. D486 is widely used in the flotation of nonferrous and precious metal ores, such as copper, gold, copper-gold, and lead-zinc ores, and serves as an effective alternative to Cytec 636/633.

Principles and Effects

D486 works by selectively targeting graphite, organic carbon, and free carbon, rendering their surfaces highly hydrophilic. This prevents these carbonaceous materials from adsorbing reagents, competing in flotation, or covering the surfaces of target minerals. As a result, target minerals can efficiently interact with collectors, allowing for effective recovery. This process not only improves the concentrate grade and recovery rate of target minerals but also reduces the necessary amounts of collectors and frothers.

Product Details

• Packaging: Available in 25 kg bags and 750 kg bulk bags.
• Usage and Dosage: The recommended concentration of the prepared solution is less than 3%. It is added during flotation, typically in the mixing tank, flotation cell, or ball mill. Suggested dosages range from 50 to 1000 grams per ton of raw ore.
• Preparation Method:
  1. Add water to the mixing bucket and begin stirring.
  2. Slowly introduce the D486 reagent into the water, ensuring full dispersion.
  3. Continue stirring for 1-2 hours until the reagent is fully dissolved in the water.

Benefits of D486 in Flotation

Separating graphite and organic carbon from sulfide minerals is challenging due to graphite's high floatability and low hardness. Traditional processes often involve decarbonization followed by flotation, which can lead to the loss of target minerals, higher operational costs, and complications in tailings water reuse.

D486 provides a solution by selectively inhibiting graphite and organic carbon, allowing direct flotation of target minerals without the need for pre-decarbonization. Key benefits include:

• Prevention of Mineral Loss: By inhibiting carbonaceous materials, it reduces the loss of valuable minerals during flotation.
• Simplified Tailings Water Reuse: The selective inhibition of graphite simplifies tailings water management and reuse.
• Enhanced Recovery and Concentrate Grades: Selective carbon inhibition leads to higher recovery rates and concentrate grades.
• Reduced Reagent Consumption: By improving flotation selectivity, it reduces the need for high volumes of collectors and frothers.

Summary

D486 is an advanced depressant that significantly enhances the efficiency and effectiveness of the flotation process for nonferrous and precious metal ores. Providing a cost-effective and environmentally friendly alternative to traditional methods, D486 helps achieve better concentrate quality and recovery rates while streamlining operational costs and environmental management.
