The research, development, and application of novel, highly efficient, and low-toxicity mineral processing reagents serve as the core technological foundation for realizing green mineral processing and enhancing the overall competitiveness of the mining sector. The Challenges of Traditional Reagents and the Need for Green Transformation Over the past few decades, classic mineral processing reagents—such as xanthates, dithiophosphates, and amines—have played a pivotal role in industrial production. However, as ore characteristics become increasingly complex and national environmental regulations grow stricter, the limitations of these traditional reagents have become increasingly apparent: many traditional reagents possess a certain degree of toxicity; during use, they can contaminate tailings water, thereby posing a threat to both the ecological environment and human health. Even commonly used xanthates exhibit relatively poor biodegradability, and their residues can adversely affect aquatic life. To address these challenges, Y&X—drawing upon forty years of extensive experience in the mineral processing industry—has developed a series of flotation reagents specifically designed to tackle the difficulties associated with floating complex ores. These reagents are characterized by their "high efficiency, low toxicity, biodegradability, and strong selectivity." YX09510C Used as a collector for copper sulfide minerals, this reagent exhibits extremely strong collecting power. Under low-alkalinity conditions, it demonstrates weak collecting power toward pyrite and pyrrhotite. It also possesses strong separation capabilities for complex copper-zinc ores, significantly improving the recovery rates of precious and rare metals—such as gold and silver—associated with copper sulfide minerals. YX3418A-5 Characterized by strong frothing properties and powerful collecting capabilities. It exhibits strong collecting power toward copper sulfides and precious metals (such as gold and silver), as well as pyrite, while demonstrating weak collecting power toward lead sulfide minerals. Suitable for use under both acidic and alkaline conditions, it can be utilized independently or in combination with xanthates. When applied to iron ore desulfurization, it adapts well to acidic environments and effectively removes pyrrhotite and pyrite; when applied to copper sulfide ores, copper-gold sulfide ores, and gold ores, it enables higher recovery rates for copper and gold. It is not suitable for high-sulfur copper ores. YH240 An effective collector for copper and gold ores. It enables the flotation recovery of oxidized and acid-soluble copper minerals that are otherwise difficult to process. It also exhibits high selectivity toward pyrite and flotation-active gangue minerals, thereby allowing for increased collector dosages—facilitating the extraction of difficult-to-float copper and gold minerals without compromising concentrate quality. It is most frequently used in combination with primary collectors, such as xanthates. The adoption of novel, highly efficient, and low-toxicity mineral processing reagents not only enhances beneficiation efficiency but also significantly mitigates environmental risks, yielding substantial economic and social benefits.

Zinc oxide ores have long been considered among the most difficult to process. Due to their complex mineralogy, fine dissemination, and surfaces often coated with oxide films, traditional collector systems designed for sulfide ores frequently fail to achieve efficient recovery. During flotation, the strongly hydrophilic nature and poor natural floatability of zinc oxide minerals lead to issues such as low reagent adsorption efficiency, unstable froth, and suboptimal recovery rates. In practical operations, many processing plants struggle to balance concentrate grade and recovery, even after adjusting grinding fineness, pH levels, and frother systems. This not only increases reagent consumption but also directly impacts the overall economic efficiency of the beneficiation process. In response to this industry pain point, Y&X has developed YX300S, a high-efficiency zinc collector specially used for zinc oxide ore flotation. This product can effectively enhance the hydrophobicity of the mineral surface and improve the selective adsorption capacity of zinc oxide minerals, thereby significantly improving the flotation index, reducing the dosage of chemicals while increasing the recovery rate and concentrate grade, helping the dressing plant achieve more stable and economical production results. Y&X carries out a zinc oxide mine project in Morocco, using original ore samples. After the ore samples were crushed and mixed, mineralogy analysis samples and mineral processing test samples were obtained respectively. Table 1 shows the results of the analysis of lead, zinc and elements affecting mineral processing. Table 2 shows the lead phase analysis results and Table 3 shows the zinc phase analysis results. From the results of multi-element analysis and phase analysis, it can be seen that the recovered elements in this mineral are mainly Pb and Zn.The content of CaO and MgO in the raw ore is relatively high. Through microscopic analysis, it is mainly dolomite with a small amount of calcite. The floatability of dolomite is similar to that of sphalerite, which makes it difficult to recover zinc oxide.Mineral Processing Process DesignThrough extensive flotation experiments, it has been found that dolomite and calcite have significant adverse interference on zinc oxide flotation, and the reagents cannot effectively interact with zinc oxide. In situations where the consumption of reagents is very high, it is also difficult for zinc oxide to be effectively floated. To address this issue, efficient zinc oxide collectors and efficient depressants for dolomite and calcite have been developed, optimizing the mineral processing technology. The specific beneficiation process involves grinding the material to -0.074mm, with a proportion of 75%. The first step is flotation of lead sulfide, and the second step is flotation of zinc oxide.Flotation of Lead Sulfide: In the lead flotation stage, a coarse selection is used, and the bottom stream of the coarse selection is fed into the sweeping operation. Collectors are added to the sweeping operation, and the tailings after three rounds of sweeping are the final tailings; The foam of roughing is fed into the cleaning operation, and three times of cleaning are carried out to obtain Lead concentrate products.Flotation of Zinc Oxide: The tailings from Lead Sulfide flotation are fed into Zinc Oxide flotation. Firstly, a gangue depressant is added, followed by the addition of sodium sulfide and a high-efficiency Zinc Oxide collector for Zinc Oxide coarse selection; The roughly selected bottom stream is fed into the sweeping operation, which adds sodium sulfide and Zinc Oxide high-efficiency collectors. The tailings after three rounds of sweeping are the final tailings; The foam of roughing is fed into the cleaning operation, and sodium sulfide + depressant is added into the cleaning operation. Three times of cleaning are carried out to obtain zinc oxide concentrate products.Test ResultThe analysis of the experimental results is shown in Table 4. The grade of Lead Concentrate obtained from closed-circuit testing is 55.66%, with a recovery rate of 78.30%; The grade of Zinc Oxide concentrate is 38.15% and the recovery rate is 84.49%. Efficient Zinc Oxide Collector YX300S: Zinc Oxide is an efficient collector with certain foaming properties, mainly used for the flotation of Zinc Carbonate and Sphalerite, which can effectively avoid the interference of mud gangue minerals on Zinc Oxide flotation. The flotation process is stable and the recovery of Zinc Oxide is good.ConclusionThe final flotation process flow will be determined for the flotation test of Moroccan Zinc Oxide ore samples. The proportion of grinding fineness -0.074mm is 75%; The Lead flotation stage adopts one coarse selection, three fine selections, and three sweeping selections; The Zinc Oxide flotation stage adopts one coarse selection, three fine selections, and three sweeping selections. The grade of Lead concentrate obtained through closed-circuit testing is 55.66%, with a recovery rate of 78.30%; The grade of Zinc Oxide concentrate is 38.15% and the recovery rate is 84.49%.
