Description

Artificial jade and manufacture method thereof based on red mud

Technical field

The invention belongs to the artwork production field, is to utilize the industrial solid castoff that produces in the aluminum oxide production process specifically---artificial jade and manufacture method thereof that red mud is produced.

Background technology

Red mud is the industrial solid castoff that produces in the aluminum oxide production process, and one ton of aluminum oxide of general every production promptly produces about 1.0-1.3 ton red mud.Enterprise generally adopts the mode of air storage to handle red mud, and this has taken a large amount of soils on the one hand, on the other hand, and objectionable impurities meeting polluted underground water and ambient air in the red mud, thereby to the serious harm of ecotope generation.

For many years, people have adopted multiple technologies that red mud is fully utilized, as therefrom extracting useful chemical composition, being raw material production building materials etc. with the red mud, but all there is defective to a certain extent in these technology, as still can produce industrial solid castoff after extracting useful component, and when extracting useful component, generally need to add a certain amount of reactant, the amount of the waste of Chan Shenging is also more than red mud so under many circumstances; Also there are problems such as quality instability, energy consumption height in application facet in building materials.

For these reasons, active demand in the market is to new technology, the novel process of red mud comprehensive utilization.The contriver of this patent promptly is engaged in the development work of artificial jade from April, 2009, has developed multiple products such as artificial white jade, black jade, jasper, carbuncle, and excellent property has broad application prospects at jewellery and artwork field.
