为了有效利用天草的低耐火度陶石,对其低耐火度的原因进行了脱除长石提高品位的研究。证实用粘土浮选和长石浮选组合的二段浮选从低耐火度陶石中可以脱除长石。进而,对不同采矿工作面产出的低耐火度陶石进行粘土浮选的结果表明,由于捕收剂浓度不同,不同试料的粘土矿物的回收率显
In order to make effective use of Amakusa low refractory ceramic, its low refractoriness reasons for the removal of feldspar to improve the grade. It was confirmed that flotation can be removed from low refractory pottery by a two-stage flotation using a combination of clay flotation and feldspar flotation. Furthermore, the results of clay flotation of low refractory ceramics produced at different mining work surfaces show that the recoveries of clay minerals from different samples were significantly different because of the different collector concentrations
