Method for removing calcium from high-calcium black talc
The invention discloses a method for removing calcium from high-calcium black talc, and relates to the technical field of chemical engineering, and the method for removing calcium comprises the following steps: S1, preparing black talc ore, screening the ore in a magnetic separation manner to remove magnetic impurities and increase the purity of the black talc ore, and crushing, ball-milling and sieving the screened black talc ore with a 100-mesh sieve to prepare black talc powder; s2, adding water into the black talcum powder to form slurry; s3, performing a hydrochloric acid content adding test, and analyzing based on big data to obtain the influence of proportioning results of different hydrochloric acid contents on the slurry, so as to obtain the optimal hydrochloric acid adding content; adding industrial hydrochloric acid into the slurry, and reacting for 30 minutes; the method for removing calcium from the black talc is low in cost, high in efficiency, free of pollution, simple in process and suitable for industrial application, the problem that the content of calcium in the black talc is too high and the problem of pollution emission in the treatment process can be solved, the mining economic benefits are improved, and better industrial use prospects are brought.
本发明公开了一种高钙黑滑石中除钙的方法，涉及化工技术领域，除钙步骤为：S1、准备黑滑石矿石，将矿石经过磁选的方式进行筛选，筛去磁性杂质，增加黑滑石矿石的纯度，将筛选后的黑滑石矿石经破碎、球磨、过100目筛制成黑滑石粉；S2、向黑滑石粉中加入水，形成泥浆；S3、进行盐酸含量添加试验，基于大数据分析得出不同盐酸含量的配比结果对泥浆的影响，得到最佳的盐酸添加含量；向泥浆中加入工业盐酸，反应30min。本发明提出的黑滑石除钙方法，成本低廉，效率高，零污染，工艺简单，适合工业应用，能够解决黑滑石中钙含量过高的问题与处理过程中污染排放的问题，提高开采经济效益，带来更好的工业使用前景。
