摘要
对宜丰某花岗岩型锂矿选矿后尾砂进行矿物组成、物化性能等分析测试,其主要成分为石英、钠长石和微斜长石,烧成白度为58.4%,密度为2.53 g/cm^(3),耐火度为1144℃,通过开展日用陶瓷坯釉料配方烧成试制。结果表明,以尾砂用量为30%配以其他地区主要原料时适合还原焰1310℃一次烧成坯釉料配方,其白度为67.4%,光泽度为81.5,吸水率为0.2%,釉面硬度为6.2 GPa,抗热震性为180~20℃热交换一次均未裂,成瓷性能达到GB/T 3532—2009《日用瓷器》合格品要求。本研究为该区或同类型矿床选矿后尾砂资源的综合利用提供了参考。
This experiment involved conducting mineralogical and physicochemical analyses on the post-beneficiation tailings of a granite-type lithium deposit in Yifeng.Its primary constituents include quartz,albite,and microcline,with a firing whiteness of 58.4%,a density of 2.53 g/cm^(3),and a refractoriness of 1144℃,the firing trials were carried out to assess the suitability of these tailings for formulating glazes used in daily-use ceramic production.The findings suggest that a glaze formulation suitable for one-time firing at 1310℃under reducing flame can be achieved by incorporating 30%of the tailings with other primary raw materials from different regions.Its whiteness is 67.4%,gloss is 81.5,water absorption rate is 0.2%,glaze hardness is 6.2 GPa,and the thermal shock resistance is that it can withstand 180-20℃thermal exchange without cracking once.The ceramic properties meet the"Tableware Porcelain"of GB/T 3532—2009 standard requirements for qualified products.This research provides reference for the comprehensive utilization of tailings resources following ore beneficiation in this region or similar types of mineral deposits.
