Design of Gold and Silver Smelting Factory
Gold and silver smelting is a traditional industry and the process is mainly mechanical. Due to the low requirement of physical properties, there are fewer traditional processes. Smelting is divided into three stages: pre-treatment, smelting and refining.
First of all, before smelting, the raw materials of gold and silver melt need to go through a process of crushing and grinding, so as to make them small enough for subsequent processing. Secondly, for smelting process, normally 1250℃ is appropriate temperature and a good atmosphere is needed. Finally, in the refining process, the slag, waste and impurities of gold and silver through U-shape flue and bucket wheel should be removed.
The setting of smelting factory is determined by the site, equipment and technology. Generally, the gold and silver smelting process should be accomplished step by step in the enclosed space.
The site selection of the smelting factory must be appropriate, which plays a key role in the long-term operation of the factory. Taking into account the needs of different stages of the smelting process, places with good transportation, better local environment and resources should be selected. Also, the smelting factory needs a special reception area for solid raw materials and liquid products, with suitable scales and balance.
In terms of equipment, the smelting factory use furnaces, special molds, heat insulation material, condensers, scrubbers and drainage system, weighing machine and slag cleaning equipment. In addition, according to the amount of raw materials and products, the size and configuration of the equipment should be selected.
The technology adopted in the smelting process is the melting and purifying technology of gold and silver, which requires reasonable control of time, temperature and atmosphere in the furnace. Additionally, the smelting process in should be taken place in an enclosed space equipped with advanced dust removal systems and efficient condensers, so as to reduce air pollution.
To conclude, the design of the gold and silver smelting factory requires reasonable site selection and reasonable configuration of equipment and technology. Only by taking into account all aspects of the design, such as reasonable control of time, temperature and atmosphere in the furnace, to ensure its better operational performance and economic efficiency. 。
