Abstract. A method is proposed for converting number frequencies of unsieved heavy minerals to weight percentages. If the grain count is made by a method, such as the ribbon count method, that gives an unbiased estimate of the number frequency of a mineral, the conversion involves multiplying the number frequency of the mineral in a given microscopically measured size class by a density or

Heavy Minerals an overview ScienceDirect Topics

Under normal plant flow conditions, the sorting characteristics of typically equant heavy minerals e.g., rutile, zircon and ilmenite is generally predictable, but the settling rates of detrital gold grains are much more difficult to assess and each gold ore should always be treated as a special case. Although denser than most other placer minerals, gold grains have much wider size, shape
