【摘要】 高岭土是一种重要的非金属矿产资源,是豫北地区的优势矿产之一。矿体赋存于石炭系中统本溪组中上部,具有较好的成矿条件,层位稳定,厚度较大,具有较大的远景储量。高岭土常含有铁、钛等着色杂质,影响其烧结白度及其他性能,限制了其应用。因此,对高岭土含杂及除铁除杂增白的技术研究尤为重要。通过分析豫北地区高岭土矿资源状况,探讨高岭土矿资源综合利用途径,为豫北地区矿产资源规划及矿业经济可持续发展提供科学依据。更多还原

【Abstract】 Kaolin,a superior resource in north Henan province,is kind of important non- metallic mineral resource. The ore bodies occur in upper part of Middle Benxi Group in Carboniferous system with characteristics of good minerogenetic conditions,stable horizon,large thickness and large prospective reserves. Because of the content of colored impurities like iron and titanium,its sintering whiteness is decreased and other properties are greatly affected,which limit its industrial application. Therefore,the study on analysis of impurities and removal of them for whiteness improvement is critical in industry. A comprehensive study has been conducted on kaolin resources in north Henan province to explore new methods for kaolin resource utilization,and provide a scientific basis for mining resources planning and sustainable development of mining economics in this area.更多还原
