Method for preparing mineral wool fibers from leaching residues of hydrometallurgy laterite-nickel ore and application of mineral wool fibers
The invention discloses a method for preparing mineral wool fibers from leaching residues of hydrometallurgy laterite-nickel ore and application of the mineral wool fibers. According to the method, leaching residues of the hydrometallurgy laterite-nickel ore are adopted as a raw material, a conditioning agent is added into the raw material, normal-temperature solid-state mixing and conditioning are performed to enable the acidity coefficient to be greater than or equal to 1.2, and then mixed material melting, discharging and filamentation are performed to obtain the mineral wool fibers; or, the leaching residues of the hydrometallurgy laterite-nickel ore are used as raw materials, and the raw materials are fused, discharged and filamented to obtain the mineral wool fibers. The method can reduce solid waste and environmental pollution, is used for preparing rock wool, improves the heat insulation performance of buildings, improves the energy utilization rate and reduces energy consumption.
本发明公开了一种利用湿法冶金红土镍矿的浸出渣制备矿物棉纤维的方法及其应用，所述方法为：以湿法冶金红土镍矿的浸出渣为原料，在原料中添加调制剂，常温固态混合调制使酸度系数≥1.2，然后将混料熔融、出料、成丝得到矿物棉纤维；或，以湿法冶金红土镍矿的浸出渣为原料，将原料熔融、出料、成丝得到矿物棉纤维。该方法可减少固废，降低环境污染，用于制备岩棉，提高建筑隔热保温性能，提高能源利用率，降低能耗。
