摘要
We propose a method for leaching nickel, cobalt and iron from a nickel laterite ore, characterized in that the nickel laterite ore is brought into contact with a solution of sulphuric acid and urea mixture. In this way, there is provided a method for efficient recovery of nickel and cobalt from nickel laterite ores where leaching in sulphuric acid/urea mixture can be completed in about less than 1 hour.
