摘要

本文介绍了含铜页岩接触角的测量方法。在缩醛、吡啶水溶液和蒸馏水存在的条件下，采用固滴法和俘获泡法测定了进、退接触角的值。两种方法均表明，被测物质对含铜页岩表面疏水性(以接触角表示)的影响较小。经试验证明，缩醛和吡啶均不能归类为捕集剂，因为它们都不能改善含铜页岩的疏水性。这些试剂只是浮选起泡剂。

Contact angle of copper-bearing shales using the sessile drop and captive bubble methods in the presence of selected frothers

This paper describes the measurement of contact angle of copper-bearing shales. The values of advancing and receding contact angles were determined using the sessile drop and captive bubble methods in the presence of aqueous solutions of acetal and pyridine and distilled water. Both methods demonstrated that the tested substances had only minor impact on the surface hydrophobicity of copper-bearing shales expressed by contact angle. The tests carried out proved that neither acetal nor pyridine may be classified to the collecting reagents because none of them improves hydrophobicity of copper-bearing shales. These reagents are only flotation frothers.
