Tests were conducted to compare the performance of detergent FD-602 and nitric acid in cleaning the copper concentrate ceramic filter plate in Tonglushan Mine in Hubei Province. The results show that after being cleaned with FD-602, the ceramic filter plate has cleaner surface and its filter cake also presents uniform adsorption during filtration. After being cleaned using FD-602 and nitric acid, the ceramic filter can produce 6.63 t/h and 5.85 t/h filter cakes on average, with average moisture of 11.21% and 11.58%, respectively. Every ton of filter cake consumes 0.16 kg and 1.78 kg detergent, with the cost of 6.4 yuan and 5.696 yuan, respectively. When the cleaning water collected from the FD-602 cleaning process mixed with domestic water at a ratio of 1∶5 is returned to flotation process, it is shown that there is no obvious influence brought to the flotation performance.
