Artificial soil based on copper tailing modification and preparation method thereof
The invention discloses artificial soil based on copper tailing modification and a preparation method thereof. The artificial soil is prepared from the following components in parts by mass: 100 parts of copper tailings, 10 to 20 parts of bagasse fiber, 4 to 8 parts of low-alkali cement, 0.2 to 0.4 part of aggregate accelerant, 0.06 to 0.10 part of drought-resistant water-retaining agent, 0.4 to 0.8 part of acidity regulator and 5 to 10 parts of microbial fertilizer. According to the invention, the copper tailings are used as a main raw material, and other components are doped to modify the copper tailings, so that the copper tailings have physicochemical properties and nutritional components required by plant growth, the artificial soil for ecological restoration can be produced by using local materials on mines, precious natural soil resources are not consumed, the purpose of treating wastes with wastes is realized, the cost of copper mine ecological environment restoration and treatment is reduced, pollution caused by tailing stockpiling is reduced, and the ecological environment of a mining area and the surrounding of the mining area is improved.
本发明公开了一种基于铜尾矿改性的人造土壤及其制备方法，该人造土壤包括以下质量比组成分：铜尾矿100份、甘蔗渣纤维10～20份、低碱水泥4～8份、团粒促进剂0.2～0.4份、抗旱保水剂0.06～0.10份、酸度调节剂0.4～0.8份、微生物菌肥5～10份。本发明以铜尾矿为主要原料，再掺入其它成分对铜尾矿进行改性，使其具备满足植物生长所需的理化性质和营养成分，可以在矿山上就地取材的生产用于生态修复的人造土壤，不消耗宝贵的天然土壤资源，实现“以废治废”，降低铜矿山生态环境恢复治理的成本，减少尾矿堆存的污染，改善矿区及其周边的生态环境。
