Abstract

The invention discloses a formula of black craft ceramic. The black craft ceramic comprises the following components in part by weight: 30 to 40 parts of manganese slag, 15 to 20 parts of low-grade bauxite, 20 to 25 parts of quartz powder and 30 to 35 parts of yellow clay. The discarded manganese slag and the low-grade bauxite are adopted as ingredients to produce the black craft ceramic, and industrial waste materials which are difficult to utilize formerly are effectively treated, so that the black craft ceramic with higher art appreciation and collection value is obtained through production, the production cost is low, and the problems that the pileup of the waste materials occupies plenty of land and causes the pollution to the ambient environment are solved. The resource of the ingredients is wide, the cost is low, the reutilization of solid waste resources can be realized, and implementation effect is ideal.

Description

technical field [0001] The invention relates to a formula and a production process of ceramics, in particular to a formula of black technical ceramics and a production process thereof. Background technique [0002] During the production process of manganese metal extraction, a large amount of water-quenched manganese waste residue will be produced, which is rich in SiO 2 、Al 2 o 3 , MnO 2 At present, a small amount of materials such as manganese are used as raw materials for building materials, and most of them are piled up and discarded, resulting in a huge waste of resources. At the same time, the stacking of water-quenched manganese waste residues also takes up a lot of land, and it is easy to pollute the surrounding environment. The reuse of manganese waste residue is also an important issue. Low-grade bauxite is solid waste in the bauxite mining process. Since the aluminum oxide contained therein does not reach the industrial grade, it is treated as solid waste dur...
