Highlights

Because of its light weight，high strength，and good corrosion resistance，the development and application of titanium have attracted widespread attention from Chinese and foreign scholars.The higher the content，the lower the grade of titanium concentrate that can be recovered，and it is difficult to improve the recovery rate.In order to improve the recovery efficiency of ilmenite，the heating behavior of ilmenite under pulsed microwave conditions was studied.In this study，pulsed microwave pretreatment of ilmenite was carried out using a self-made pulsed microwave device.The effects of different irradiation time，pulse microwave power，weight of ore sample and particle size of different ore samples on the heating performance of ilmenite were studied.The composition of the ore sample was analyzed by X-ray diffractometer，and the particle size of the sample was detected by a nano-laser particle size analyzer.The research results show that the heating behavior of materials in the microwave field is determined not only by the nature of the mineral itself，but also by the power of the microwave heating equipment.The temperature increase rate of ilmenite is significantly affected by the quality of the sample.At the same time，the change law shows consistency under different heating time conditions：When the mass of ilmenite is 40~60 g，the temperature increase rate reaches the maximum.The changes in the quality of ilmenite can significantly affect the heating temperature of the ore sample.Under the condition of a certain microwave power，the longer the microwave acts on the material，the higher the temperature of the ore sample.With the change of the particle size of the material，the microwave temperature showes a trend of increasing first and then decreasing.When the ore sample has a particle size of 25 mm，a weight of 40 g，an irradiation time of 30 s，and an average microwave power of 3 kW，the sample is heated to the best effect.The research in this paper is of great significance for the application of pulsed microwave in the field of grinding aid.

全国矿产地质志研编取得阶段性进展

2020年7月，全国及各省（区、市）第一部全面总结域内现代矿产地质工作科学成果，特别是中华人民共和国成立以来矿产勘查与研究成果的志书——全国矿产地质志研编目前取得阶段性进展。截至7月10日，累计完成92部志书成果报告。其中，正式出版33部志书。

矿产地质志研编项目于2014年正式启动，由中国地质科学院矿产资源研究所组织实施，全覆盖我国矿种、矿产地、国域面积，最终提交涵盖全国32个省区市（含台湾）的志书、全国性46个重点矿种志书和重点区带志书约150部。

据介绍，目前该项目取得的阶段性进展，一是初步清理和核实了全国矿种和矿产地，形成了64 846处矿产地的数据集，编制了中国矿产地分布全图（2020版），基本摸清了中国矿产资源的分布特征。

二是通过对全国46个重点矿种志书研编，系统总结每个矿种的资源禀赋特征、开发利用情况、时空分布特征、典型矿床和成矿机制、成矿模式和成矿规律、成矿预测等，初步形成覆盖全国重点矿种的矿产资源保障体系。目前已完成19部全国性单矿种志书，其中正式出版10部。

三是系统总结各省域内矿产资源现状，初步摸清了各省区市矿产资源家底，目前共完成35部省级志书（含1套省级专题图件，25部省级单矿种志书），其中正式出版发行10部；首次部署在全国范围内开展矿产地质普及本编写，目前共完成18部，其中正式出版发行9部。

四是部署了全国94个Ⅲ级成矿区带的成矿规律系统总结，实现了我国领土、领海面积的全覆盖，对20个重点区带成矿规律志书进行研编，目前共完成10部区带志书，其中正式出版发行1部。
