Collector Liquid Xanthates HYDR420 and HYDR620 Properties
Collector HYDR420 is a highly effective reagent designed for the flotation separation of lead-zinc sulfide ores, copper-zinc sulfide ores, and copper-lead-zinc sulfide ores. This reagent primarily consists of xanthate esters, with an active content above 80%, and appears as a yellow to brown liquid. It serves as a liquid alternative to traditional solid xanthates and MBT, offering significant convenience and efficiency in mineral processing.
Known for its strong collecting power for copper and lead, HYDR420 significantly improves the grade and recovery rates of these concentrates while reducing the zinc content in copper-lead concentrates. Its weak collecting power for pyrite and pyrrhotite makes it particularly suitable for high-sulfur copper ores and high-sulfur copper-gold ores, reducing the need for lime or sulfur depressants. Additionally, HYDR420 is highly effective in collecting cerussite without prior sulfidization, enhancing its convenience and application scope.
In contrast, Collector HYDR620 is a robust and versatile mineral processing reagent with an active mineral processing substance content of over 90% and this yellow oily liquid is insoluble in water. HYDR620 stands out as a strong, non-hazardous substitute for xanthates, suitable for use across a wide pH range (4-12). It is particularly effective for the flotation of challenging sulfide ores containing copper, lead, zinc, and nickel. The product’s stability and efficiency in low recovery rates of fine particles and in scenarios of overgrinding of molybdenite and galena make it an good choice for improving concentrate grades.
Due to its insolubility in water, HYDR620 is not easily adsorbed by gangue minerals such as clay, talc, and chlorite, further enhancing its effectiveness. Under acidic conditions, HYDR620 exhibits strong collecting ability for pyrite, making it highly effective for pyrite flotation and iron ore desulfurization. Its efficiency surpasses that of xanthates, requiring only 50% to 80% of the dosage typically needed. Additionally, HYDR620 is highly effective in collecting precious metals such as gold and silver, serving as a primary or auxiliary collector for these minerals.

What are the Advantages of Liquid Xanthate Compared to Solid Xanthate?
When comparing liquid xanthates like HYDR420 and HYDR620 to solid xanthates, their advantages become evident. Liquid formulations offer greater convenience in handling and application, requiring no dissolution prior to use and allowing for direct addition to flotation circuits. This eliminates the need for additional preparation steps and reduces operational complexity. Moreover, liquid collectors like HYDR420 and HYDR620 often exhibit improved efficiency and effectiveness in flotation processes, providing desirable collecting power and nice performance in varying ore conditions compared to their solid counterparts. Their wider applicability also contribute to their preference in modern mineral processing operations.
In summary, both Collector HYDR420 and HYDR620 offer significant advantages in the field of mineral processing. Collector HYDR420 provides strong collecting power for copper and lead, improves concentrate grades, and reduces the need for additional depressants, making it a versatile and convenient option. Collector HYDR620, with its robust and non-hazardous composition, offers excellent efficiency and versatility for a wide range of challenging sulfide ores, enhancing concentrate grades and improving overall flotation performance. These unique properties and efficient performances make liquid xanthate HYDR420 and HYDR620 invaluable tools for mineral processing applications.
