对矿物起疏水作用的捕收剂与起亲水作用的抑制剂,它们的结构对于它们在矿物表面的吸附极关重要,因而对它们的工艺活性也是非常重要的。在此项研究中,首先对链烷羧酸的结构用-Br及-COOH进行取代而加以改变。由结构改变而引起的吸附特性的改变,可以捕收剂表膜中的二聚作用、解离、缔合以及极性基与矿物表面的作用为基础加以解释。研究中,应用了各种能与碱土金属矿物形成螯合物的肪族和香芳族化合物来作抑制剂。药剂分子中极性基团的种类、数目和位置以及药剂表膜的结构对药剂的抑制效能起着决定性的作用。
Collectors that act as hydrophobic agents for minerals and inhibitors that act as hydrophilic agents, their structure is crucial for their adsorption on mineral surfaces and therefore their process activity is also very important. In this study, the structure of the alkanecarboxylic acid was first changed with -Br and -COOH. Changes in the adsorption properties caused by structural changes can be explained on the basis of the dimerization, dissociation, association, and the role of polar groups and mineral surfaces in the collector’s membrane. In the study, various kinds of aliphatic and aromatic aromatic compounds that can form chelates with alkaline earth metal minerals were used as inhibitors. The type, number and location of polar groups in the drug molecule and the structure of the drug membrane play a decisive role in the effectiveness of the drug.
