Copper tailings brick
Gray sand brick
May Copper Mountain mine tailings discharged annual production of 75 000 t, is currently stockpiling capacity of 1.1 million t, this copper mine tailings are mainly of quartz sand by the dozen mineral which, after technical analysis to prove No comprehensive recovery value. The mine has been extensively tested using tailings to make bricks and has been successful.
First, the nature of raw materials
From the data of sand used in domestic lime sand brick factory, the main component of silica is generally not less than 65%, and the harmful component mica should not be too high. The main chemical composition of tailings in this mine is SiO 2 60.43%, Al 2 O 3 14.27%, Fe 2 O 3 4.69%, CaO 6.22%, MgO 1.40%, K 2 O 3.4%, Na 2 O 3.86%, basic Meet the requirements for brick making.
Second, the production process
The tailings and lime are used as raw materials (adding coloring agent admixture), prepared by blanking, compression molding, and saturated autoclave curing.
The gauze bricks produced have been inspected and the quality has reached the ministerial standard. The appearance indicators are first-class bricks, and their technical indicators exceed those of red bricks. Its utilization prospects are broad.
