Rotary Dryers in Nickel Laterite Ore Preparation
The Need for Nickel Laterite Dryers. While drying is a common first step in many mineral processing operations, it is essential when it comes to laterites, which are typically surface mined in the tropics and can contain up to 30% moisture. ¹. This high moisture content gives laterites a wet and sticky quality, which makes further processing ...
