What is the difference between gangue and ore? Quora

Answer Wiki. Gangue is valueless mineral associated with a valuable mineral that can economically be utilized, which is an ore . e.g. pyrite (FeS2) will be a gangue mineral associated with say sphalerite (ZnS) if the latter mineral can be utilized commerciallylikewise, quartz/calcite will be gangue minerals associated with say an ore of copper.

The tensile strength of soil is very low or negligible and in most analyses it is considered to be zero. In contrast a number of direct or indirect tensile strength tests are commonly carried out for rock. In a direct tensile strength test a cylindrical rock specimen is stressed along its axis by means of a tensile force.
