摘要
江西省某钾长石矿赋存于燕山早期某斑状花岗岩体半风化带内,钾长石矿物(斑晶)呈松散粗大颗粒状,经筛选可从风化岩石中分离出来,使其成为可利用的矿物。该矿为省内一处新型钾长石矿资源产地,采用"选矿分级-磨矿分级-重选-高梯度磁选"物理方法,可使长石精矿中的Fe2O3含量降至0.10%以下,达到了国际同类产品的先进水平。在陶瓷、玻璃等非金属产品领域有广阔应用前景,为我国长石产品精矿生产开辟了新的途经。
The K-feldspar ore in Jiangxi Province exists in half-weathered zone of the porphyritic formed in early Yanshanian. The feldspar minerals (phenocryst) are loose large granules. They can from the decayed rock. This ore is a new type of resources in Jiangxi Province. The Fe2O3 content in the drop to below 0.10% by the physical method of "ore-dressing granite body be separated feldspar may grading - ore-griding grading - gravity separating - high gradient magnetic separating", and becomes the similar product with the international advanced level. The K-feldspar ore has the broad application prospect in the nonmetallic product field such as pottery, porcelain, glass and so on, its application sets up a new path for K-feldspar product ore concentrating products in our country.
