Abstract

The invention relates to a high temperature chlorination shaft furnace, and belongs to chloridizing roasting shaft furnaces in the metallurgical industry. Raw materials are calcium chloride containingpellets, gold, silver, copper, lead, zinc, tin and cobalt in metallurgical and beneficiation waste residues can be extracted, and oxidation pellets can be produced. The high temperature chlorinationshaft furnace comprises a feeding device, a roasting chamber, burning chambers, a cooling discharging device and a chlorination metal gas discharging device. The burning chambers are located on one ortwo sides of the roasting chamber, and communication is achieved through a flame path. Extraction openings are located on one or two sides of the lower portion of a feeding opening, the high temperature chlorination shaft furnace is high in temperature rising capacity, sensitive in temperature controlling, even in heating, not prone to nodulation and good in product quality coincidence, and a nodule destroying device is arranged.

Description

technical field [0001] The invention relates to high-temperature chlorination process production equipment, in particular to a chlorine-containing pellet roasting shaft furnace. Background technique [0002] The high-temperature chlorination method can be used for the extraction of gold, silver, copper, lead, zinc, cobalt, tin and other metals in tailings and smelting slag. Ball machine or briquetting machine granulates, and the obtained agglomerates are roasted after being dried. The metal elements in the smelting slag except iron and silicon volatilize in the form of chlorides at high temperature, and can be taken out with the high-temperature flue gas. [0003] The process of processing raw materials into pellets for high-temperature chlorination usually uses a rotary kiln as a roaster. The rotary kiln is composed of a cylinder body, a wheel belt, a supporting wheel, a retaining wheel, a transmission device and a sealing device at the kiln head and the kiln tail. The c...
