黄麦岭磷矿是一大型沉积磷灰岩矿床,目前开采的是风化矿。为了提高选矿效果,根据开采技术和矿石的自然类型,将磷矿石分为四类,其中D类矿为混合矿,选矿难度较大,单用H869、氧化石腊皂选别指标都很差,如果采用H869:氧化石腊皂=3:1混合用药分选D类矿,或者使H869与南平塔尔油以7:1混合分选A类矿,都能获得较好的生产指标。详见下表。 在国外混合用药强化浮选极为普遍,大型选矿厂无一不采用混合用药。国内金属矿山对混合用药也比较重视,对磷矿选矿混合用药也引起注意,只是对其机理的探讨不够。
Huangmeiling phosphate rock is a large sedimentary apatite deposit, the current exploitation of weathering mines. In order to improve beneficiation results, according to mining technology and the natural type of ore, the phosphate rock is divided into four categories, of which D ore is a mixed ore, dressing more difficult, alone H869, Oxide Paraffin sorting indicators are poor , If the use of H869: Oxalisate soap = 3: 1 mixed drug class D ore, or make H869 and Nanping Tallow mixed with a 7: 1 Class A ore, can get better production targets. See the table below. In overseas mixed drug intensive flotation is extremely common, large-scale concentrator all use mixed medication. The domestic metal mines also pay more attention to the mixed medicine, and also pay attention to the mixed medicine of the phosphate rock dressing, but the study of its mechanism is not enough.
