Abstract:In the process of mineral processing, accurate detection of ore-pulp pH and suitable feeding of lime are the most important factors affecting the stability of flotation process. Taking the intelligent construction of Chengmenshan Copper Mine concentrator as an example, a new online pulp pH detector is developed and the screw pump is used to add lime slurry. On this basis, the intelligent adjustment system of flotation pulp pH is successfully constructed, which is of great significance and is worthy of reference for the domestic industry and even related industries reference resources.
