Research Of Artistic Glaze By Using Gold Ore Tailings

In this paper, gold ore tailings were used as raw material to prepare piebald glaze. This glaze has special decorative effect that made it use widely in the ceramic industries. Using tailings produced new material that not only benefited to the comprehensive management of waste, but also protected the environmental and improved economic development. This project has good prospects for the development and utilization.Dehua was one of three porcelains in china. We selected three representative enterprises, carried out a number of experiments for researching formula, and then get three series, nine varieties of artistic glaze products. Including medium temperature kiln glaze, piebald glaze, glazed in warm colors, low temperature frit glaze, matt glaze and other ceramic glazes. Preparation process would consider gold ore tailings effected green strength, expansion coefficient, water absorption, glazed gloss, hardness, compressive strength in principles and mechanisms. Through scientific computing, explore the impact of various factors on the technical specifications of the glaze, determine the optimum production process.Fujian Wanqi technical Ceramics limited company is a modern art Home Furnishing high-tech enterprises. Color glaze was using widely in the process. Its products were bottle and jar and ceramics for daily using and processing ceramics. Firming temperature of products can be 1280±5℃.We add 56% Gold ore tailings into semi finished ceramic material, of which the optimum amount of tailings in glaze and green body are 15wt% and 51wt%, Making a large of experiments determined transmutation glaze formula: SiO2:Al2O3=2.59, acidity coefficient: CA=0.77, the glaze effect was of light area. According to the company’s value invested the tailings, expected recoverable gold tailings 100,000 tons.The way of using gold ore tailing prepare piebald glaze and medium temperature color glaze was implied in Fujian Quanzhou Shunmei Group Co.Ltd.. This method was aimed at products for daily use ceramic and technology ceramic. The firing temperature is 12220±10℃, of which the optimum amount of tailings in glaze and green body are 22wt% and 36wt%, glazed gloss was 46% and 41%. Making a large of experiments determined the glaze formula:SiO2:Al2O3=3.99, Acidity coefficient: CA=0.37. These values of the glaze were basically consistent with the theoretical.Quanzhou Fujian Province Peng-Lung coporation produced ceramics by using iron ore tailings, iron ore tailings accounted for 28% of all the raw materials. The use of iron ore tailings preparation cryogenic secondary glaze and matte glaze frit, the firing temperature is 1020±5℃, of which the optimum amount of tailings in glaze and green body are 44wt% and 27wt%, glazed gloss are 66. Making a large of experiments determined matt glaze formula: SiO2:Al2O3=9.7.Experiments show that ceramic body formulations may be added up to 56% of tailings, glaze formulation amount of up to 27%, which will create a new way to deal with tailings problems and reduce the cost of production of ceramic.
