Method for preparing baking-free brick from laterite-nickel ore high-pressure acid leaching smelting tailings and baking-free brick
The invention provides a method for preparing a baking-free brick from laterite-nickel ore high-pressure acid leaching smelting tailings and the baking-free brick. The method comprises the following steps that S10, the laterite-nickel ore high-pressure acid leaching smelting tailings are subjected to dehydration treatment and crushing treatment; s20, the crushed laterite-nickel ore high-pressure acid leaching smelting tailings are mixed with a certain amount of aggregate, cement and water, mixed slurry is obtained after uniform stirring, and then the mixed slurry is pressed into green bricks; and S30, curing the pressed and molded green brick for a period of time to prepare the baking-free brick. According to the method, the laterite-nickel ore high-pressure acid leaching smelting tailings, aggregate and cement are prepared according to a certain proportion and then pressed into bricks, and resource utilization of the laterite-nickel ore high-pressure acid leaching smelting tailings can be achieved.
本发明提供一种利用红土镍矿高压酸浸冶炼尾渣制免烧砖的方法及免烧砖，该方法包括以下步骤：S10：对红土镍矿高压酸浸冶炼尾渣进行脱水处理和破碎处理；S20：将破碎后的红土镍矿高压酸浸冶炼尾渣与一定量的骨料、水泥和水混合，搅拌均匀后得到混合浆料，然后将所述混合浆料压制成砖坯；S30：压制成型的砖坯养护一段时间后制成免烧砖。该方法通过将红土镍矿高压酸浸冶炼尾渣、骨料和水泥按一定比例配制后压制成砖，可实现红土镍矿高压酸浸冶炼尾渣的资源化利用。
