I work in flotation and I read this book nearly every day. It’s lighter reading than a typical literature paper but it’s certainly loaded with details and can be a complex read. However, it covers basic information about the flotation of each mineral and it cites examples of real operations. Then the descriptions of chemical schemes and conditions and reactions add a lot of depth, this is where the complexity and rereading comes in. You can continue to add detail to your understanding of the conditions affect the reactions which affect the flotation recovery. This book definitely earns the title of “handbook”.
