Description

Spodumene magnetic purification equipment and method Technical Field The application relates to the technical field of spodumene mineral separation, in particular to a magnetic purification device and method for spodumene. Background The main process of spodumene dressing is a "flotation process", i.e. the rough spodumene concentrate is obtained by "coarse grinding-desliming-multistage flotation". However, this process has the following drawbacks and deficiencies that cannot be resolved: Firstly, the impurity removing capability is limited. Conventional flotation is mainly based on the separation of silicate minerals (spodumene) and the surface chemical property differences of gangue such as feldspar and quartz, but has poor separation effect on iron-containing silicate minerals (such as petalite, tourmaline and iron-containing amphibole) with the floatability similar to that of spodumene and iron minerals embedded with micro-fine particles, so that the iron content in concentrate is difficult to effectively reduce. Secondly, the medicament system is complex and the environmental protection pressure is high. In order to improve the sorting effect, a plurality of regulators, inhibitors and collectors are often added, the medicament system is complex, the subsequent tail water treatment difficulty is high, the cost is high, and a certain environmental risk exists. Thirdly, the recovery effect on the fine particle fraction is poor. Spodumene or iron-containing mineral micro-fines produced during the grinding process are vulnerable to loss from tailings or entry into concentrate during flotation, causing fluctuations in grade and reduced recovery. Fourth, the product stability is poor. Fluctuations in raw ore properties (e.g. iron-bearing mineral species, variation in the particle size of the embedded), can significantly affect the flotation effect, leading to an unstable final concentrate quality (especially iron content). The above-mentioned several disadvantages all lead to the purification effect of spodumene.
