Abstract

The invention relates to a combined flow treatment method of tin rough concentrate, belonging to the technical field of non-ferrous metal ore-dressing and metallurgy. The process flow comprises the following steps: preparing pulp containing the tin rough concentrate; feeding the tin rough concentrate subjected to the pulp preparation into a magnetic separator for dressing magnetic minerals; making sulfide minerals float out of non magnetic ore by a floating operation; sorting by using a table concentrator to obtain qualified tin rough concentrate and a lean middling ore product; combining a magnetic mineral and lean middling ore obtained by magnetic separation; and treating a mixture by a direct current submerged arc furnace to obtain tin dioxide soot and primary iron ingot. By adopting an ore-dressing and metallurgy combined process flow, the method greatly simplifies the ore-dressing and concentrating process flow. Iron products are treated by the direct current submerged arc furnace, so that not only tin metals of the iron products can be recovered, but also the primary iron ingot can be obtained and iron metals can be recycled while improving the tin recovery rate; and the invention improves the resource utilization rate and has favorable application and popularization prospect.

Description

Technical field:

[0001] The invention relates to a combined treatment method of tin rough concentrate and belongs to the technical field of non-ferrous metal beneficiation and metallurgy. Background technique:

[0002] In the past ten years, due to the decreasing resources of easy-to-separate tin ores, the nature of the ore processed in production and processing has become increasingly complex, and the ore selectivity has become worse and worse, and the mineral processing indicators have declined year by year. In order to ensure the quality and recovery rate of tin concentrate products, almost all tin concentrators adjust the beneficiation process to the rough selection stage to select tin rough concentrate containing 8-20% tin, and the rough concentrate is sent to the concentrate. The beneficiation system selects qualified tin concentrate with a grade greater than 40% and Fuzhong ore with a tin content greater than 3.5%. The qualified concentrate is handed over to the smelt...
