Anshan-type hematite accounts for about 55.20% of the total identified iron ore resources in China, and its flotation generally requires high temperature (about 35 ℃ or more) conditions, which increases the production cost. Therefore, the flotation behavior of hematite and quartz was studied with a self-developed MY-type collector and compared with the sodium oleate flotation system. Utilizing detection and analysis techniques such as contact angle, Zeta potential and infrared spectroscopy analysis, the action mechanism of MY on mineral surface was discussed. The results of single-mineral flotation experiments show that under the temperature range of 15-35 ℃, the pH of 11.5, and the dosage of 200 mg/L, the MY-type collector can achieve recovery rate of quartz and hematite exceeding 87.25% and 92.50% respectively. At 25 ℃, under the interaction of the three agents of starch, CaO, and collector, the maximun difference in single mineral recovery rate of quartz and hematite is 89.25 percentage points under the MY flotation system, which significantly improves the difference in the flotation of quartz and hematite compared to the sodium oleate flotation system (the maximun difference in recovery rate is 56.25 percentage points). The mechanism analysis results indicate that MY collector exhibits multifaceted synergistic adsorption effects on quartz mineral surfaces, including electrostatic adsorption, hydrogen bonding, and chemical bonding, while on hematite surfaces, it primarily involves molecular adsorption and electrostatic adsorption. Due to the presence of multiple active groups such as S＝O, —NH₂ and C＝O in its structure, MY forms coupled synergistic interactions across multiple active sites, enhancing its quartz recovery capability. This also amplifies the floatability difference between quartz and hematite, effectively promoting the separation of hematite and quartz in the room-temperature reverse flotation system.

鞍山式赤铁矿在我国已探明的铁矿资源总储量中占比约为55.20%，其在浮选时一般需采用加温（约35 ℃以上）条件，增加了生产成本。采用自研的新型捕收剂MY进行赤铁矿、石英浮选行为研究，并与油酸钠浮选体系进行了对比，通过接触角、Zeta电位和红外光谱等检测分析手段，探讨了MY在矿物表面的作用机理。单矿物浮选结果表明:MY在15~35 ℃温度范围内，pH为11.5，捕收剂用量为200 mg/L条件下，石英、赤铁矿回收率分别可达87.25%、92.50%以上。在25 ℃时，在淀粉、CaO、捕收剂3种药剂相互作用下，MY浮选体系下，石英、赤铁矿单矿物回收率最大差值为89.25个百分点，相较于油酸钠浮选体系（回收率最大差值为56.25个百分点）明显提高。机理分析结果表明，MY捕收剂在石英矿物表面发生了静电吸附、氢键作用以及化学键合作用等多效协同吸附作用，在赤铁矿表面以分子吸附、静电吸附作用为主。MY因其结构中存在S＝O、—NH₂、C＝O等多种活性基团，可形成多活性位点的耦合协同作用，增强其对石英的捕收能力，并增大了石英与赤铁矿间的可浮性差异，在常温反浮选体系中可有效促进赤铁矿与石英的分离。
