Abstract:

The bauxite deposits in Henan province features multi-origins, multi-forms and multi-facies. The bauxite deposits are complicated in modalities, making difficult in study and mining. There are some issues, short in shallow reserve, lacks in deep exploration, environmental pollution, resources wasted, deficient in study on coexisting elements, and low utilization extent. According to national policies, this paper suggests enhancing the geological study, improving comprehensive utilization of coexisting elements, applying deep exploration, optimizing bauxite resources allocation, and developing extensively alumina manufacturing.

Key words:

摘要：

河南铝土矿形成具有多源、多态、多相和多变的特征。铝土矿形态复杂，给铝土矿地质研究和开发利用带来困难。开采利用过程中，存在地表储量不足、深部资源勘查欠缺、资源浪费与环境污染、伴生元素赋存状态研究不足与开发利用程度低等问题。根据国家有关政策精神，建议加强铝土矿分布规律、伴生元素赋存与利用、深部资源勘探与采矿技术等研究工作，搞好铝土矿资源配置，集约发展氧化铝工艺。
