A mined mineral must not have undergone any change in its molecular structure through heating or combining with other substances. Acceptable if the material is not processed or fortified with synthetic chemicals. Mined minerals are regarded as supplements to a balanced organic soil building program. Some of the minerals that are mined can also be made synthetically or are by-products of industry; investigate the source of any new material.
