Yangquan Mining District is a major location for anthracite coal production in China Understanding the modes of occurrences of major and trace elements in Yangquan coal is significant both geochemically and environmentally although most elements are more depleted than those in Chinese coal NEW OCCURRENCES OF MINERALS AT IRON MOUNTAIN MISSOURI 739 tempts were made to prepare some of it for chemical analysis by hand-picking and by using the electromagnet and heavy solutions but hema-tite stains permeate all the material collected so that an accurate quanti-tative determination of the iron present as actinolite is impossible
