Grinding flotation of bituminous coal of different

10/09/2015· Grinding is proved to be an effective method to improve the flotation of oxidized bituminous coal because of the creation of fresh hydrophobic surfaces. More ultra-fine particles formed by grinding and easier re-oxidization don't deteriorate the grinding flotation performance. The grinding time should be prolonged as the oxidation degree of coal increases. It is also discovered that for mild
