Red mud be bauxite through various physics and chemical treatment, produce aluminum oxide after remaining reddish brown toner mud shape, high-moisture, alkaline solid waste, alumina producing enterprise adopts the mode of storing up of building a dam to handle red mud mostly, and stacked arrangement has wet method, semidrying, dry method etc. multiple.According to the production method difference of aluminum oxide, red mud generally is divided into red mud from sintering process and Bayer process red mud, and its quantum of output is different because of ore grade, production method, state of the art, in aluminum oxide production process, and 1.0～1.8 tons of red muds of 1 ton of aluminum oxide output of every production.Domestic alumina-producing method mainly contains: integrated process (the in parallel or series connection of sintering process and bayer's process), sintering process and bayer's process, wherein, sintering process is called soda-lime sintering process again, needing to add a large amount of lime prepares burden, utilize the high temperature bayer's process of domestic ore (being mainly diaspore type) also need add a certain amount of lime and carry out stripping, and utilize the low temperature bayer's process of external ore (being mainly gibbsite type) when stripping, not need to add lime.Red mud composed as follows:
Bayer's process last red mud weight is formed: SiO
218-25%, Fe
2O
328-35%, Al
2O
318-25%, Na
2O 8-12% and CaO2-4%;
Sintering process last red mud weight is formed: SiO
215-20%, Fe
2O
312-15%, Al
2O
36-9%, Na
2O 2-3% and CaO 35-45%.
Calcium oxide and dioxide-containing silica are higher in the red mud from sintering process, calcium oxide is generally about 40%, in the mineral composition based on beta-dicalcium silicate, the condense composition and the performance of condensing with some cement, and later strength height, be easy to pile up and build a dam, the red mud from sintering process of domestic aluminum oxide enterprise output adopts the wet method mode of storing up of building a dam to handle in the open.This method is simple, prove that through long-term practice its operation, technical qualification are very ripe, the highest dam body can be built more than 70 meters, first red mud dump of the application unit discharging red mud from sintering process is during nearly 50 years storing up, can keep safe and stable operation, and red mud dam, stockyard is in good condition at present always.Bayer process red mud contains higher ferric oxide and aluminum oxide, mineral composition is based on pyrrhosiderite, rhombohedral iron ore, calcium aluminosilicate hydrate (high temperature Bayer process red mud), owing to do not contain beta-dicalcium silicate, its gelling is relatively poor, utilize the high temperature bayer's process of domestic ore owing to when stripping, add lime, calcium oxide content is about 20% in the red mud, higher relatively, can adopt semidrying or the dry method mode of storing up of building a dam to handle mostly in the open, but loose, not fixed, the easy landslide of the red mud of building a dam, dam body is built highly difficult very big; Utilize the low temperature bayer's process of external ore owing to do not add lime during stripping, calcium oxide content is extremely low in the red mud, have only about 3%, the cohesion of red mud and permeability coefficient are all far below the high temperature Bayer process red mud, cause store up the back intensity too low, the red mud dewatering is poor in addition, can't build a dam at all, has the enterprise of sintering process technology to take red mud is pumped into the method processing that the sintering process flow process is prepared burden.Along with the low temperature bayer's process aluminum oxide output of utilizing external ore improves constantly, the sintering process production line is if continue the increasing Bayer process red mud of digestion, become no longer economical, the aluminum oxide enterprise that perhaps has does not have the sintering process flow process at all, the road that Bayer process red mud can only be walked to store up.Because this Bayer process red mud is difficult to build a dam, erecting the dam stacks Bayer process red mud more on every side in the stockyard earlier must to use other material, a kind of damming method is to adopt the red mud from sintering process wet method to build a dam, another kind of damming method is directly to build a cubic meter dam, the cost of building a dam is higher, therefore, the stacking problem of Bayer process red mud is the difficult problem of puzzlement alumina producing industry always.
