The invention relates to the technical field of
solid waste
resource utilization, in particular to glass ceramics made from high
silicon iron
tailings, which is characterized by comprising the raw materials in parts by weight: 30-70 parts of the iron
tailings, 15-40 parts of
quartz, 5-20 parts of
calcium carbonate, 3.5-6.5 parts of aluminum
oxide, 8.5-9.5 parts of
sodium carbonate, 4-5 parts of
zinc oxide, 3-6 parts of
barium carbonate and 1-3 parts of
borax. The manufacturing method of the glass ceramics comprises the following steps: putting the glass ceramics blended materials in a
kiln for melting into
molten glass; allowing the
molten glass to directly flow into water for water
quenching to form glass particles; and paving the glass particles in a
refractory die, crystallizing the paved particles in a
tunnel kiln, a shuttle
kiln or a chamber electric furnace, and
grinding and
cutting the crystallized glass ceramics to finally obtain the finished product of the glass ceramics. The invention can reduce
stockpile of the
tailings, alleviate environmental
pollution, realize comprehensive
resource utilization, improve product performances and lower production cost, thus having good social benefit and good economic benefit.
