【供应铜矿砂黑金沙黑亮砂金刚砂石英砂薛先生136/6726/9191】江苏省扬州市徐州市黑金沙铜矿砂在哪儿

金属类工业用途：喷砂、除锈、研磨等。

其他用途：印刷工业研磨胶版，以及轻工业加工塑样，皮革，砂纸等用途。

天然金刚砂的磨削力略低于电炉白刚玉，但其韧性强，具有介壳状段口之特性，其优点是磨件的光洁度高，砂痕少而浅。磨面细而均匀，可提高产品质量，为本品的独特之处。天然金刚砂的研磨时间短，效益高，价格低廉，可弥补寿命短的不足。铜矿砂粒度砂适用范围 喷砂抛光研磨地坪耐材一、铜矿砂简介：

铜矿砂又名铜炉渣，是从铜矿中开采后，经过选矿冶炼分离提取铜后产生的炉渣，也叫熔渣。再经破碎、筛选按不同用途和需要分规格加工而成，成为含铜品质较高、精细的颗粒或砂状铜矿。铜矿砂的种类主要有黑色铜矿砂和白色石英砂两种。以黑铜矿砂的应用为主。

1. Brief introduction of copper ore:

Copper ore is also known as copper slag. After mining from copper mine, the slag produced after separation and extraction of copper through mineral processing is also called slag. After crushing and screening, it is processed according to different uses and requirements, and becomes a high quality and fine grain or sand shaped copper ore with high copper quality. There are two kinds of copper ore sand: black copper ore and white quartz sand. The application of black copper ore is mainly.二、铜矿砂理化指标：

三、铜矿砂性能特点：

铜矿砂颗粒硬度高，外形棱角多，磨削快，可溶性氯离子含量低，喷砂时破损率小，含灰率低，粉尘极少，无环境污染，提升了喷砂工人的工作条件，铜矿砂除锈效果优于其它除锈砂，价格低廉，并且可以重复循环利用多次，由于可以反复利用，随即降低了工厂的成本，其经济效益大幅度提升。

Three. The properties of copper ore sand:

Copper sand particles with high hardness, shape edges, grinding speed, soluble chloride content is low, when blasting damage rate is small, low ash content, little dust, no environmental pollution, improve the working conditions of workers sandblasting, derusting copper sand is better than the other sand cleaning, low price, and can be reused many times. As can be used repeatedly, then reduce the cost of the plant, which greatly enhance the economic benefits.
