A method of precipitating copper sulphide from an incoming feed stream comprising copper liberated from within battery materials can includes the steps of: a) receiving an incoming feed stream comprising copper entrained in a carrier liquid in a precipitation apparatus; b) introducing a sulphide reductant to the feed stream to precipitate copper sulphide solids out of the feed stream during a precipitation residence time that is less than 24 hours to produce a copper sulphide slurry; and processing the copper sulphide slurry to separate the precipitated copper sulphide solids and provide a copper-depleted stream.
