G.H. Luttrell, in The Coal Handbook: Towards Cleaner Production: Coal Production, 2013. Abstract: Coal preparation plants incorporate a variety of separation processes that operate in relatively independent parallel circuits. The identification of optimum cutpoints for each circuit that globally maximize plant performance have historically involved the use of mathematical simulation routines.

Today, not one of these dense-medium plants remains operational. Spirals were introduced into the South African coal industry in the early 1980s and soon became accepted as the fine coal beneficiation process of choice. Currently, almost every coal processing plant in South Africa employs spirals to beneficiate fine coal.
