Abstract. Reactions in the process of flotation occur on the interface between minerals. Hence, the structure and properties of the solid–liquid interface play an important role in the flotation that determines the adsorption of flotation reagent on the mineral surface. The adsorption of water molecule on the MoS2 (001), Sb 2 S 3 (010), Cu 2
Y&X Beijing Technology Co., Ltd. was established in August 2014. Y&X company is a member of the family mining group which has been engaged in the mining industry for 30 years. The group owns many mines such as iron, copper, phosphorus, molybdenum, gold, lead and zinc, and has qualifications of geological exploration, mining ore dressing design
A range of companies make flotation reagents and flotation equipment for the mineral-processing industry. Mining Magazine talked to some of the main players about mining projects that they have supplied, and any recent product releases ArrMaz is constantly improving reagent performance by plant testing. In this image, it is setting up to run

flotation is typically quite low (15 - 25 %Sn) in comparison to that obtained from the gravity circuit. Reagents and operating conditions are selected to suit the ore and the local conditions. What works well at one mine can often be ineffective at another. As at other tin mines

flotation, another key tool is a “selectivity criteria” or the index of the desired metal versus an undesired metal, Gaudin’s Selectivity Index is such an index. (Taggart 1945). Test series are limited in the conceptual phase of flowsheet design and frequently tests are not duplicated. Test series focus more on various reagent combinations

Different flotation principles mean different flotation reagent systems. Based on more than 20 years of mineral processing practice and experience, Xinhai mine research institute has summarized several experiences as follows: Easiness to hardness, that is, float the easy-floating minerals first, then float the difficult-floating minerals
Jun 08, 2016 The flotation reagents can be added in a feed-forward fashion based on the plant raw coal tonnage. Automatic feedback control of the flotation reagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the froth cell tailings. Expensive nuclear-based sensors have been tried with limited success
