    The invention uses machine-vision to improve the performance of a flotation operation to provide a substitute for conventional human vision and problem-solving abilities. The invention redirects the conventional approach of ''characterising the froth'' to ''measuring the froth characteristics''. The invention provides a method of monitoring and controlling a mineral mixture flow in a froth flotation cell of a flotation plant which includes the steps of obtaining a series of digital images extracted of froth characteristics from a flotation cell. The digital images are transmitted to a computer for processing thereof into parameter signals of digital parameter froth characteristics. Control signals are produced in response to parameter signals received for causing required variations in froth characteristics in a flotation cell; and the froth characteristics in the flotation cell are controlled in response to the control signals so as to cause required variations in the froth characteristics in the cell.
