Title: A froth flotation method and a froth flotation arrangement
Inventor: MIETTINEN TATU
IPC: B03D1/02
Filed: 2017-07-04
Abstract: The invention is based on the idea of a froth flotation method for treating mineral ore particles suspended in slurry, comprising a flotation tank for separating the slurry into an underflow (19) and an overflow (20). The arrangement comprises a primary line comprising at least three flotation tanks connected in series, wherein each subsequent flotation tank is arranged to receive the underflow (19) from the previous flotation tank. The method comprising the steps of: feeding a slurry (8) to a tank (2) through a slurry inlet (15), the tank (2) has at least 200 m3 volume, and the tank (2) comprises an available froth surface area (Afroth). The tank (2) comprises a froth collection launder (7) comprising a froth overflow lip (6), and the overflow lip (6) has total length of the overflow lips (L tot) in horizontal direction (x). There is an effective height (h) from a bottom (5) of the tank to the lip (6) of the froth collection launder (7). The tank has a diameter (D) at the height of the impeller, where the diameter of the tank is calculated as an average at the height of an impeller (h3). The ratio between the effective height (h) and the diameter (D) of the tank (h/) is less than 1,5. Introducing gas bubbles to the tank through a gas supply (4), mixing the slurry (8) and the gas with the impeller (3) within the tank (2), and capturing the valuable material from the slurry (8) to the gas bubbles creating a froth (12). The third tank or subsequent tank in the series comprises a ratio L tot/ √A froth between a total length of the overflow lips (L tot) in horizontal direction (x) and a square root of an available froth surface area (A froth) is 4-20. The method further comprises the steps of: causing the froth (12) to flow over the froth overflow lip (6) of the froth collection lauder (7) by controlling the froth level (14), wherein the froth overflow lip (6) of the third tank or subsequent tank in the series comprises an edge portion (13) with variable height (h) in the vertical direction (y), and controlling the froth level (14) to be vertically higher than the vertically lowest edge height (h1) of the lip (6) and vertically lower than the vertically highest edge height (h2) of the lip (6), and controlling the slurry level (17) to be lower than the vertically lowest edge height (h1) of the lip (6). The application also relates to a froth flotation arrangement.
