The study on the tailings' comprehensive utilization is mainly concentrated in minerals in the past, which means we need to use all kinds of research methods and results that we use in the mineralogy nowadays. Maybe we can break away from the research bondage of the modern mineral technology, tracing back to the genesis of the mineral deposits from the genesis of mineral formation, especially some sedimentary deposits, which we can call "natural metallurgical field," so that we can probably get some new technologies and methods of the tailings' comprehensive utilization. On the other hand, after re-understanding of the varieties of deposit types and the occurrence states of metal elements, we can select the corresponding technology to recover associated components according to different types of deposits tailings, which will maximize the recovery rate of associated components.
