| titleOfInvention | The method of processing copper concentrates into copper matte in a shaft furnace |
| abstract | The method of processing copper concentrates in a shaft furnace into copper mattenon the fact that the copper concentrate, as well as converter slag, coke and sodium slag formednin the recovery of lead from shaft and converter dust captured in the processesnof copper production, is introduced into a furnace and melted, and the resulting top is tapped intonclarifier, where the copper matte is separated from the shaft slag, characteristicnin that the sodium slag is introduced into the shaft furnace in a mixture with converter slagnfrom refining copper matte and copper-iron-lead alloy, slagnsoda in the form of castings and / or in the form of ground is poured in liquid slag pitsnconverter slag in a weight ratio from 1: 2 to 1:14, then it is cooled and grinded and sonthe resulting mixture in an amount of 8-2% by weight in relation to the briquette amountnThe copper concentrates are introduced into a shaft furnace and the melting process is carried out atncoke content of 4 - 12% by weight in relation to the amount of copper concentrates and blastnof air in the amount of 40 - 65 m3 per 1 m2 of air of the furnace cross-section at the nozzle level per minutenwith the efficiency not exceeding 90 Mg of copper-bearing charge per 1m7 of the cross-sectional areanthe furnace at the nozzles daily, and after melting, the top flowing into the decanter is dischargednwith a slag layer thickness of not less than 0.5 m. |
