Why recycle solid waste alumina?
Solid waste alumina, also known as red mud, is a byproduct of the production of alumina from bauxite ore. It contains various metallic oxides and minerals such as iron oxide, titanium dioxide, and silica. Recycling solid waste alumina has become an important issue due to its environmental impact. lM Series vertical roller mill applied for solid waste alumina recycling process plant
Firstly, recycling reduces the amount of waste that ends up in landfills or disposed of in water bodies. Red mud disposal can lead to soil contamination and acidification which affects crop yields and drinking water quality.
Why recycle solid waste alumina?
Secondly, recycling reduces the need for mining new ores to extract aluminum. Bauxite mining causes significant ecological disruption like deforestation, loss of biodiversity and habitat destruction for rare species.
Thirdly, recycled solid waste alumina is a valuable resource that can be used in construction materials like bricks making them lighter yet stronger than traditional options.
Recycling solid waste alumina helps reduce greenhouse gas emissions while conserving natural resources and reducing negative impacts on human health.
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
