摘　　要：分析了长石类型、用途及相应的选矿方法，对某钾长石矿进行了脉动高梯度磁选除铁试验研究，结果表明，在磁场强度７３２ｋＡ／ｍ、冲次１００次／ｍｉｎ，冲程１５ｍｍ、流速２５０ｍｌ／ｓ条件下经一次磁选可获得含铁０．１７％、钾钠回收率９６．９４％的钾长石精矿，满足了用户对铁含量要求小于０．２％的标准。The types,uses and processing methods of feldspar are analysed in this paper.A test on removing ferro by pulsating high gradient magnetic separation to the potash feldspar is introduced.Result shows that the potash feldspar concentrate with 0.17% Fe,K Na recovery of 96.94% have been obtained by once magnetic separation under suitable condition,and the concentrate can meet consumer's demand——ferro content less than 0.2%.
