Abstract: Methods for removing a soluble heavy metal-sulfur complex from a process solution comprise contacting the process solution with an oxidant to oxidize the heavy metal-sulfur complex and form an oxidized complex precipitate, or with an acid to acidify the heavy metal-sulfur complex and form an acidified complex precipitate, and removing the precipitate from the process solution to provide a heavy metal-reduced solution. The method is advantageous for removing heavy metals such as mercury, cadmium, barium, iron, vanadium and/or manganese from process solutions, for example originating from natural gas production, petroleum production, water treatment or mining.

Abstract: A method for treating process water of a flotation arrangement (1) is disclosed, the flotation arrangement comprising flotation arrangement (1) comprising a mineral flotation line (10) and a process water treatment arrangement (20) for treating underflow of the mineral flotation line. The method comprises the steps of a) dewatering underflow from the flotation in a gravitational solid-liquid separator (21); b) subjecting supernatant (221) from step a) to cleaning flotation for collecting at least fine particles and residual flotation chemicals, for separating at least fine particles and residual flotation chemicals from the supernatant into cleaning flotation overflow (232), and for forming purified process water (231) as cleaning flotation underflow; c) removing cleaning flotation overflow (232) as tailings, and d) recirculating purified process water (231) into the mineral flotation line (10).
