技术领域technical field
本发明涉及矿物浮选技术领域，尤其涉及一种循环利用高硬度废水和浮选调控的方法。The invention relates to the technical field of mineral flotation, in particular to a method for recycling high-hardness wastewater and flotation regulation.
背景技术Background technique
背景技术中的下列内容仅指本发明人理解的与本发明有关的信息，旨在通过对与本发明相关的一些基础技术知识的说明而增加对本发明的理解，该信息并不必然已经构成被本领域一般技术人员所公知的知识。The following content in the background technology only refers to the information related to the present invention understood by the inventor, and aims to increase the understanding of the present invention by explaining some basic technical knowledge related to the present invention. Knowledge known to those of ordinary skill in the art.
矿物加工工程是一门分离、富集、综合利用矿产资源的技术科学。主要利用矿物的物理或物理化学性质的差异，借助各种选矿设备将矿石中的有用矿物与脉石矿物分离，并达到有用矿物相对富集的目的。从而具备多种分选方法，例如，利用物理性质的重选、磁选、电选等，以及利用矿物表面润湿性的浮选。其中，以浮选应用最为广泛。浮选涉及到固、液、气三相体系。从而，导致关注度远不及含砷、氟、磷等废水的高硬度废水，在矿物加工工程领域也是不得不考虑的问题。其主要原因在于：硬度的提高会导致管道以及设备结垢堵塞，需要人工进行不定期敲打，严重的甚至造成损害。以及随着水硬度的上升，会导致浮选药剂的用量的上升，从而增加经济成本。另外，浮选在使用一定的浮选药剂后，自身也会带来一定的高硬度废水，处理起来又成为企业的一部分成本，从而如何让高硬度废水与浮选建立良性关系显得至关重要。Mineral processing engineering is a technical science of separation, enrichment and comprehensive utilization of mineral resources. It mainly utilizes the differences in the physical or physical and chemical properties of minerals, and uses various beneficiation equipment to separate the useful minerals in the ore from the gangue minerals, and achieve the purpose of relative enrichment of useful minerals. Therefore, it has a variety of separation methods, such as re-separation, magnetic separation, electric separation, etc. using physical properties, and flotation using mineral surface wettability. Among them, flotation is the most widely used. Flotation involves a three-phase system of solid, liquid and gas. As a result, high-hardness wastewater that is far less concerned than wastewater containing arsenic, fluorine, phosphorus, etc. is also a problem that has to be considered in the field of mineral processing engineering. The main reason is that the increase of hardness will lead to fouling and clogging of pipes and equipment, requiring manual irregular beating, and even causing damage in severe cases. And as the water hardness rises, the consumption of flotation agents will increase, thereby increasing the economic cost. In addition, after flotation uses certain flotation agents, it will also bring a certain amount of high-hardness wastewater, and the treatment will become part of the cost of the enterprise. Therefore, how to establish a benign relationship between high-hardness wastewater and flotation is very important.

进一步地，步骤（1）中，所述矿物包括辉钼矿、黄铜矿、黄铁矿等硫化矿中的任意一种。Further, in step (1), the minerals include any one of sulfide ores such as molybdenite, chalcopyrite, and pyrite.

进一步地，步骤（2）中，所述高硬度废水是指以CaCO3含量计，大于17.0mg/L的水。可选地，所述高硬度废水与一次尾矿形成的矿浆浓度为20~30%。Further, in step (2), the high-hardness wastewater refers to water with a CaCO 3 content greater than 17.0 mg/L. Optionally, the concentration of the slurry formed by the high-hardness wastewater and the primary tailings is 20-30%.
进一步地，步骤（2）中，所述浮选药剂包括捕收剂和起泡剂。可选地，所述浮选药剂与一次尾矿的比例范围为10~4000g/t。Further, in step (2), the flotation agents include collectors and foaming agents. Optionally, the ratio of the flotation agent to the primary tailings ranges from 10 to 4000 g/t.
可选地，所述捕收剂包括黄原酸盐、乙硫氨酯、煤油等中的任意一种。所述起泡剂包括松醇油、甲基异丁基甲醇等中的任意一种。Optionally, the collector includes any one of xanthate, ethionate, kerosene and the like. The foaming agent includes any one of terpineol oil, methyl isobutyl carbinol and the like.
进一步地，步骤（1）中，对所述泡沫产品进行固液分离，即得一次精矿、回用水。Further, in step (1), the foam product is subjected to solid-liquid separation to obtain primary concentrate and reused water.
进一步地，步骤（2）中，对所述泡沫产品进行固液分离，即得二次精矿、回用水。Further, in step (2), the foam product is subjected to solid-liquid separation to obtain secondary concentrate and reused water.
进一步地，将上述方法中各阶段产生的回用水收集后作为所述步骤（1）中的水源，以实现水资源的循环利用。Further, the recycled water generated in each stage of the above method is collected as the water source in the step (1), so as to realize the recycling of water resources.
与现有技术相比，本发明取得了以下方面的有益技术效果：Compared with the prior art, the present invention has achieved the following beneficial technical effects:
（1）本发明在矿物浮选时加入了高硬度废水，从而通过矿物吸附高硬度废水中的钙离子，不仅降低了高硬度废水的硬度，实现高硬度废水通过浮选得到“净化”的同时，通过高硬度废水中钙离子完成调节黄铜矿与黄铁矿的表面性质差异，便于黄铜矿与黄铁矿的浮选分离。另外，通过各步骤产生的回用水收集后用于矿物浮选，从而实现高硬度废水利用与闭路循环。(1) The present invention adds high-hardness wastewater to mineral flotation, so that calcium ions in high-hardness wastewater are adsorbed by minerals, which not only reduces the hardness of high-hardness wastewater, but also achieves "purification" of high-hardness wastewater through flotation. , the difference in surface properties between chalcopyrite and pyrite is adjusted by calcium ions in high hardness wastewater, which facilitates the flotation separation of chalcopyrite and pyrite. In addition, the recycled water generated by each step is collected and used for mineral flotation, thereby realizing the utilization and closed-circuit circulation of high-hardness wastewater.
（2）本发明在选择所述高硬度废水的使用时间节点时，是在对矿物（以铜钼矿为例）进行第一次浮选（得到辉钼矿精矿和铜硫尾矿）后，对得到的铜硫尾矿再次进行浮选时才加入高硬度废水，这是由于本发明发现铜硫尾矿中的黄铁矿多高硬度废水中的钙离子具有较为强烈的吸附，而吸附了大量钙离子的黄铁矿可浮性下降。而天然黄铜矿对钙离子的吸附很弱，即高硬度废水对黄铜矿起到解抑作用。从而在此阶段加入高硬度废水后可有效改变黄铜矿与黄铁矿的表面性质差异，使两者更好地分离。(2) When the present invention selects the use time node of the high-hardness wastewater, it is after the first flotation of minerals (taking copper-molybdenum ore as an example) (to obtain molybdenite concentrate and copper-sulfur tailings) , when the obtained copper-sulfur tailings are floated again, the high-hardness waste water is added. This is because the present invention finds that the calcium ions in the copper-sulfur tailings have more pyrite and the high-hardness waste water has relatively strong adsorption, while the adsorption The floatability of pyrite with a large amount of calcium ions decreases. However, the adsorption of calcium ions by natural chalcopyrite is very weak, that is, high-hardness wastewater has a depressing effect on chalcopyrite. Therefore, adding high-hardness wastewater at this stage can effectively change the difference in surface properties between chalcopyrite and pyrite, so that the two can be separated better.

一种循环利用高硬度废水和浮选调控的方法，包括如下步骤：A method for recycling high-hardness waste water and flotation regulation, comprising the steps of:
（1）称取500g实际矿，经湿磨至-0.074mm粒级占80%，置于1.5L浮选槽进行浮选，此时浮选用水为实验室去离子水。加羧甲基钠三硫代碳酸钠4000g/t，淀粉100g/t，煤油150g/t，松醇油25g/t。从而得到钼精矿和铜硫尾矿。(1) Weigh 500g of actual ore, after wet grinding to -0.074mm particle size accounted for 80%, put it in a 1.5L flotation tank for flotation, and the water used for flotation at this time is laboratory deionized water.

从上述的实施例和对比例的测试结果可以看出，实施例1通过在矿物浮选时加入高硬水，从而通过矿物吸附高硬度废水中的钙离子，不仅降低了高硬度废水的硬度，实现高硬度废水通过浮选得到“净化”的同时，通过高硬度废水中钙离子完成调节黄铜矿与黄铁矿的表面性质差异，提高升了黄铜矿与黄铁矿的浮选分离效果。As can be seen from the test results of the above-mentioned examples and comparative examples, Example 1 not only reduces the hardness of high-hardness wastewater by adding high-hardness water during mineral flotation, thereby absorbing calcium ions in high-hardness wastewater through minerals, and realizes While the high-hardness wastewater is "purified" by flotation, the difference in surface properties between chalcopyrite and pyrite is adjusted through calcium ions in the high-hardness wastewater, which improves the flotation separation effect of chalcopyrite and pyrite.
为了进行进一步说明，进行了XPS测试。图1为黄铜矿经高硬水处理前后的XPS图谱，可以看出经过高硬度废水处理后的黄铜矿的XPS光谱中有新的峰，在346.43ev左右，属于Ca2p，从而说明黄铜矿可以有效吸附高硬度废水中的钙离子。For further illustration, an XPS test was performed. Figure 1 is the XPS spectrum of chalcopyrite before and after high-hard water treatment. It can be seen that there is a new peak in the XPS spectrum of chalcopyrite after high-hardness wastewater treatment, which is about 346.43ev, which belongs to Ca2p, thus indicating that chalcopyrite It can effectively adsorb calcium ions in high hardness wastewater.
