Jan 20, 2021 the froth flotation process is about taking advantage of the natural hydrophobicity of liberated well ground minerals/metals and making/playing on making them hydrophobic water-repel individually to carefully separate them from one another and the slurry they are in. for this purpose we use chemicals/reagents: frothers mibc is what allows the formation of air bubbles.Increase flotation yield. thus, before the flotation, process of sulfurization was made in order to change the ore structure and surface properties 9, 10 and 11. the sulfurized samples were subjected to flotation and the results were evaluated. 2. materials and method 2.1. materials.
Er, the chemistry of recycled process water may alter the performance of the flotation sys-tem. it is therefore required to understand the effects of these elements on the flotation process. electrolytes in recycled process water can hinder the collector from adsorbing onto the mineral surface wang et al, 2014; hancer et al. 2001.The effect of sulfurization process on flotation of copper flotation the effect of sulfurization process on flotation of copper ore containing gold and silver ibrahim te ğin and recep z iyadano ğullari department of chemistry, faculty of science and art, dicle university, 21280 diyarbakir, turkey fax: 90-412-2488039 tel : 90-412-2488550/3159 e-mail: [email protected] abstract flotation.
Thus, original ore was sulfurized before the flotation. by the flotation of the sulfurized ore, it was seen that au, ag, cu, zn and co were collected with fairly high yields in the concentrateflotation.
