Flotation experiments were conducted in a flotation cell (model XFD III, Jiangxi Weiming Machinery Equipment Co., Ltd, Jiangxi, China). To create a pulp density of ~28%, 400 g of lead-zinc oxide ore and a specific dosage of water were added to the flota-tion cell with a capacity of 1.5 L. The flotation machine speed was set at 1900 r/min. After

Lead and zinc mainly exist in the form of sulfide ore. At present, it is mainly obtained from lead-zinc sulfide ore [3]. Flotation, which is based on the differences in hydrophobicity of minerals, is an effectively and commonly used method for separating sphalerite (ZnS) and galena (PbS) minerals from lead–zinc ore [4], [5].

Zinc reduces tin chloride to the metallic state, and it can then be filtered off and re-dissolved in strong HCl. Experiments showed that whilst being re-dissolved there was a tendency for the tin to oxidize to stannic chloride, and in this method one is obliged to assume that the tin dissolves wholly as stannous chloride.

Process introduction. Because the density of tin ore is larger than that of symbiotic minerals, reselection methods are generally used for tin ore dressing.However, due to the presence of various iron oxide minerals in minerals, such as magnetite, hematite, etc., these minerals cannot be well separated from tin ore by reselection or flotation.
