Description
技术领域technical field
本发明涉及一种氧化铅锌矿浮选抑制剂及其应用；特别涉及含有石英和方解石的低品位氧化铅锌矿物的浮选抑制剂及其应用；属于矿物加工技术领域。The invention relates to a flotation inhibitor of lead-zinc oxide ore and its application; in particular, it relates to a flotation inhibitor of low-grade lead-zinc oxide mineral containing quartz and calcite and its application; it belongs to the technical field of mineral processing.
背景技术Background technique
我国铅锌资源储量丰富，仅次于澳大利亚居世界第二位。但是目前我国铅锌矿仅对高品位的氧化矿和少量硫化矿进行利用，大量低品位的氧化铅锌矿石无法利用。以我国最大的铅锌矿床云南兰坪氧化铅锌矿床为例，目前主要利用了硫化铅锌矿和少量锌品位高于15％的氧化铅锌矿，大量低品位氧化铅锌矿开采后则堆存与矿山附近，因浮选难度大而未有效开发，造成资源大量浪费。因此，提高该类型氧化铅锌矿的分选技术是保证我国铅锌资源供应的最重要途径。my country has rich reserves of lead and zinc resources, ranking second in the world after Australia. However, at present, only high-grade oxide ores and a small amount of sulfide ores are used in my country's lead-zinc mines, and a large number of low-grade lead-zinc oxide ores cannot be utilized. Taking the largest lead-zinc deposit in my country, the Lanping lead-zinc oxide deposit in Yunnan as an example, at present, lead-zinc sulfide ore and a small amount of lead-zinc oxide ore with a zinc grade higher than 15% are mainly used. It is stored near the mine, and has not been effectively developed due to the difficulty of flotation, resulting in a large waste of resources. Therefore, improving the separation technology of this type of lead-zinc oxide ore is the most important way to ensure the supply of lead-zinc resources in my country.
选矿技术的滞后的造成低品位氧化铅锌矿难以利用的主要原因。由于氧化铅锌矿矿石所含矿物种类较多，矿石结构关系复杂，伴生组分很不稳定，含有大量活化的石英、方解石以及可溶性盐类矿物，因此尽管氧化铅锌矿的研究已经开展了很多年，氧化铅锌矿仍然存在很多问题。The main reason why low-grade lead-zinc oxide ore is difficult to utilize is the lagging of beneficiation technology. Because the ore of lead-zinc oxide ore contains many kinds of minerals, the ore structure relationship is complex, the associated components are very unstable, and it contains a large amount of activated quartz, calcite and soluble salt minerals, so although the research on lead-zinc oxide ore has been carried out a lot In 2009, there were still many problems with lead-zinc oxide mines.
迄今为止氧化锌矿选矿技术主要采用的技术方案是硫化法或脂肪酸法，硫化法通过添加硫化钠对矿浆进行调浆处理，然后采用黄药类捕收剂或胺类捕收剂进行浮选，工艺流程上，主要采用先浮硫化矿后浮氧化矿；此法流程结构复杂，在处理大量矿泥和难免离子的矿浆时，分选效果常常不理想。氧化锌矿浮选过程中常用的抑制剂有水玻璃、六偏磷酸钠、腐殖酸、聚丙烯酸等，这些药剂在浮选的过程中添加量不易控制，对矿浆都具有强制分散作用，很不利于对后续的精矿过滤，进而造成生产过程脱水较大。Up to now, the main technical solution of zinc oxide ore beneficiation technology is vulcanization method or fatty acid method. The vulcanization method is to adjust the slurry by adding sodium sulfide, and then use xanthate collector or amine collector for flotation. In terms of technological process, it is mainly used to float sulfide ore first and then float oxidized ore; this method has a complex process structure, and the separation effect is often unsatisfactory when dealing with a large amount of slime and pulp with inevitable ions. Commonly used inhibitors in the flotation process of zinc oxide ore include water glass, sodium hexametaphosphate, humic acid, polyacrylic acid, etc. The addition of these agents is not easy to control during the flotation process, and they all have a forced dispersion effect on the pulp, which is very difficult It is not conducive to the subsequent filtration of concentrate, which will cause greater dehydration in the production process.
基于低品位氧化锌矿的特点，结合氧化锌矿浮选工艺，在药剂制度上提出了本发明。Based on the characteristics of the low-grade zinc oxide ore, combined with the flotation process of the zinc oxide ore, the present invention is proposed on the medicament system.
