Method for separating copper-containing solid waste
The invention discloses a method for separating copper-containing solid waste. The method comprises the following steps of a, performing copper-containing solid waste granulation and drying pretreatment to obtain copper-containing solid waste particles; and b, placing the copper-containing solid waste particles into an oxidation side blown converter melting pool, wherein the oxidation side blown converter melting pool temperature is 1200-1300 DEG C, melting the copper-containing solid waste particles to obtain an upper-layer gypsum melt and lower-layer copper-containing molten slag. Accordingto the method, the copper-containing solid waste with high calcium, high sulfur, low silicon and low iron characteristics can be treated, the raw material pretreatment requirement is low, the problemsof high temperature, high energy consumption, a large amount of smoke, large organic matter volatilization amount and the like of deep drying pretreatment are avoided, and the method has the remarkable energy-saving and consumption-reducing effects, and has the high treatment capacity for the copper-containing solid waste.
本发明公开了一种含铜固废的分离方法，包括如下步骤，a、含铜固废制粒和烘干预处理，得到含铜固废颗粒；b、将所述含铜固废颗粒投入氧化侧吹炉熔池中，氧化侧吹炉熔池温度为1200‑1300℃，含铜固废颗粒熔化，形成上层的石膏熔体和下层的含铜熔融炉渣。本发明的方法能够处理高钙、高硫、低硅、低铁特性的含铜固废，对原料预处理要求低，避免了深度烘干预处理的高温、高能耗、大烟尘量、有机物挥发量大等问题，具有显著的节能降耗效果，并且对含铜固废具有较大处理能力。
