The experiments were done in a box-type electric furnace, which has an excellent sealing property. The ores were firstly mixed with cokes in designed proportions, and then put into crucibles. They were then roasted in the box-type electric furnace at certain temperatures. After that, th......
The aluminium minerals and iron minerals cannot be separated by dry or wet magnetic separation. To intensify the magnetic property of Baode County¬ðs bauxite, the medium temperature magnetization roasting and then magnetic separation processing technique was adopted. ......
The experiments including: dry high intensity magnetic separation, wet high intensity magnetic separation, and medium temperature magnetization roasting and then magnetic separation are not effective for the Baode bauxite due to the nature of the ores. It is well known that the magnetic iron ......
The experiments were done in a high temperature vacuum controlled atmosphere furnace, which can be vacuumed by a specific vacuum pump, and can be filled with nitrogen or other gases needed, such as CO, that would be used in the experiments. The ores and cokes were mixed in appropriate proport......
The processes including dry high intensity magnetic separation, wet high intensity magnetic separation, and medium temperature magnetization roasting and then magnetic separation, are not effective to the Baode bauxite due to the nature of the ores, and medium temperature metallization roasti......
