摘要

Colloidal sedimentary iron deposit is the most widely distributed,the largest marine reserves sedimentary iron deposit. The geological survey has been submitted to 212 minerals,identification of iron ore reserves of 3.72 billion tons of resources,reserves of iron ore resources in China total about 6%. Such a long time because of refractory ore can not be developed and utilized. However,the mineralization of different periods and forming conditions so that the process of ore deposits are also large differences in mineralogical characteristics. Marine sediments by different types of iron ore deposits in the process mineralogy studies,the results show that: although the main iron mineral deposits such as hematite,limonite,siderite,magnetite,etc.,the main pulse minerals are quartz,oolitic glauconite,feldspar,mica,calcite,muscovite,stone marrow and so on,need to remove the minerals such as phosphate rock,but unlike deposits,its main iron mineral type and content,grain degree and nature of change is embedded in a great bout,and thus constitute a single or complex process type deposits;The gangue of quartz,calcium and magnesium mineral content to different ore deposit output pH. Deposits and various types of process classification process development and utilization of minerals is closely related to pollution of those toxic,pollution of those toxic ore mineral processing nature of technical routes with different companies at the different smelting slag,silicate component of the dressing product requirements are also different;ore the main process of iron minerals mineral characteristics change,decided to concentrate mineral product grade and recovery. This paper describes the importance of such deposit process and the pollution of those toxic classification process route selection guidance.
