Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] see figure 1 As shown, the high-efficiency and environment-friendly high-purity tin refining system in this embodiment includes: an electric furnace, a cooling flue, a dust collection room, a disc granulator, an electrolytic cell, a rectifier, and a power supply.

[0024] An electric furnace is used to smelt tin slag, burn off a small amount of metal impurities (including zinc, bismuth, etc.), and obtain large tin ingots. The temperature of the electric furnace is 2000-2500 degrees, and redox agents are added during the melting process.

[0025] A small tin ingot making device is used to m...

Abstract

The invention provides a high-efficiency environment-friendly high-purity tin refining system. The system comprises an electric furnace, a dust chamber, a disc granulator, an electrolytic tank and a power source; the electric furnace is used for smelting tin slag to obtain a large tin ingot; the dust chamber is used for collecting tin ash and feeding the tin ash to the disc granulator; the disc granulator is used for preparing the tin ash collected by the dust chamber into granules and feeding the granules into the electric furnace for smelting; the electrolytic tank is used for purifying tin ingot pieces by an electrolytic method; the power source is used for supplying power to the electrolytic tank. The high-efficiency environment-friendly high-purity tin refining system is capable of collecting the tin ash flying out in the smelting process and feeding the tin ash back for refining, and therefore, zero pollution is realized and the utilization rate of the tin slag is increased; the system is capable of purifying the tin ingot circularly to obtain high-purity tin, and has the advantages of high efficiency, environmental protection, high quality and the like. In addition, the electrolyte can be reused and zero emission of the electrolyte is realized, and therefore, the system is environmentally friendly and the loss of tin ions in the electrolyte is avoided, and the tin yield is further increased.

Description

technical field [0001] The invention relates to the technical field of tin metallurgy, in particular to an efficient and environment-friendly refining system for high-purity tin. Background technique [0002] Tin is one of the earliest metals discovered and used by human beings. The main tin-producing countries in the world are China, Malaysia, Indonesia, Brazil, Bolivia, Thailand, Peru and other countries. my country has a large reserve of tin ore resources and a long history of production. It is a major tin-producing country in the world. However, the current tin smelting systems all have defects such as low production capacity, low precision, and environmental protection, so it is necessary to improve this. Contents of the invention [0003] The purpose of the present invention is to provide an efficient and environment-friendly refining system of high-purity tin, which reduces the amount of pollutant discharge. [0004] The purpose of the present invention is achieve...
