Potassium feldspar spot crystal beneficiation method

The invention relates to a potassium feldspar spot crystal beneficiation method which comprises the following steps: carrying out rod milling, wet low-intensity magnetic separation, filtering, drying, imported high-intensity magnetic separation and secondary imported high-intensity magnetic separation on potassium feldspar spot crystals, so as to remove a harmful component Fe2O3 in the potassium feldspar spot crystals and obtain very high-quality potassium feldspar concentrate. According to the beneficiation method, the potassium feldspar spot crystals are selected through a simple technology, the potassium feldspar spot crystals can be used as potassium feldspar ore after beneficiation, the mining cost is low, the economic benefit is good, and the potassium feldspar spot crystals can be used as a new type of a potassium feldspar ore deposit. 本发明涉及一种钾长石斑晶选矿方法，通过对钾长石斑晶进行棒磨、湿式弱磁选、过滤、烘干、进口式强磁选、二次进口式强磁选，即可去除钾长石斑晶中有害组分Fe2O3，获得非常优质的钾长石精矿；该选矿方法通过简单的工艺选出钾长石斑晶，钾长石斑晶经过选矿后可以作为钾长石矿利用，开采成本低，经济效益较好，可作为钾长石矿床的新类型进行利用。
