The domain requirements such as engineering plastics, glass ceramics and organic synthesis are planted vigorous, as lithium product line industry main growth factor.Lithium carbonate is made
It will be increased every year with 8-10% speed for the basic material of lithium product, particularly LITHIUM BATTERY and high-purity level lithium carbonate speedup be more
It hurry up.Although there are two kinds of spodumene-sulfuric acid process and salt lake bittern method in production lithium carbonate China, salt lake bittern is high due to impurity content
Lithium extracts difficult, it is not easy to produce LITHIUM BATTERY and high-purity level lithium carbonate, therefore most of enterprise of China uses spodumene-sulfuric acid process
Produce lithium carbonate.But use spodumene-Production By Sulfuric Acid Process lithium carbonate per ton by about 10 tons of lithium slags of by-product, cause occupied ground
(lithium slag main component is with environmental pollution：Silica 58.37%, di-iron trioxide 0.49%, alchlor 15.34%,
Calcium oxide 6.85%, magnesia 0.68%, loss on ignition 17.62%.Lithium slag Fineness：Less than screen size 0.08MM square holes
Tail over and account for 80.5%, tail over and accounted for 4%) more than screen size 0.16MM square hole screens, constrain the development of the electric industry of lithium.Due to lithium
The transition of more than 1200 DEG C of salt slag system spodumene, acidifying, with solid phase waste residue gangue after water extraction, separating, washing, its essential mineral group
Into being aluminosilicate, and silica has turned into active silica.And match somebody with somebody first by certain component when producing portland cement
Make qualified cement slurry to be calcined, clayey raw material 6-12%, current China's cement output about 18 need to be used by preparing cement slurry
Hundred million tons/year, hundred million tons of folding year consumption clayey raw material 1-2, clayey raw material mainly have loess, clay, shale, mud stone, sandstone and
River silt etc., based on loess and clay, consumes a large amount of soils every year.The technical problem to be solved in the invention is how fully
Clayey raw material, which is substituted, using spodumene-Production By Sulfuric Acid Process lithium carbonate industry waste residue prepares cement slurry production portland cement,
Solve the problems, such as to produce lithium carbonate industrial residue, while solving the problems, such as that clayey raw material prepares the land wastage that cement slurry is caused.
