The Knelson concentrator (KC) is widely used in gold ore and other precious metal ore processing technology because of its excellent separation performance. The development history and types of KCs are reviewed in this paper. Research on the separation mechanism and characteristics of KCs was analyzed and discussed, including the separation characteristics, influencing factors, modification equipment, gravity recoverable gold (GRG) tests, mathematical models, and computer simulations. Two different configurations of a KC for the gold recovery process and the research and application status of KCs in the fields of fine coal, rare earth, platinum group metals, and other minerals were summarized. Based on our review, research trends and development prospects of KCs are proposed.
