The gangue minerals in HM deposits are generally dominated by quartz sand/silt, clay minerals, and iron-oxide minerals, with minor or rare feldspar and carbonate minerals. Specific processes of HM enrichment occur mainly in the principal zone of mineral sorting, i.e., the upper part of the beach face, also known as the swash zone …
What are mineral sands? Mineral sand deposits contain a concentrated amount of economically important minerals known as 'heavy minerals', which are much heavier than common sand minerals such as quartz. Mineral sands deposits typically comprise the following minerals of economic interest: • zircon • rutile • leucoxene • ilmenite
