Key Differences. Ore contains valuable metals or minerals that can be extracted profitably. Whereas gangue refers to the non-valuable minerals found with ore, often requiring removal during ore processing. In mining, ore is targeted for its valuable content. On the other hand, gangue is often discarded as waste, reflecting its lack of …

Gangue - Mining Fundamentals. Gangue refers to substances that are extracted along with desired minerals or ores due to their close association, and are considered commercially worthless in mining. During the mining process, the materials that are extracted are grouped into two categories - economic fraction, which is the desirable material ...

During the extraction and processing of coal, a large amount of solid waste, collectively known as gangue, is produced. This gangue has a low carbon content but a high ash content, accounting for approximately 15 to 20% of the total coal yield. Before coal is used, coal and gangue must be effectively separated to reduce the gangue content in …

Coal gangue is a mixture of a variety of rock and mineral composition with low carbon content. Normally, its calorific value increases with the increase of carbon mass fraction and volatiles, in contrast, decreases with the increase of ash. Because of the high content of SiO 2 and Al 2 O 3, the ash melting point of coal gangue is quite high ...
