In a lot of fields of the modern science and technology, the automatic monitoring system plays an increasingly important role. As regards mineral processing, in the world, the research of course automation of the mineral processing started in the 1950s, from measuring to controlling; Control and control from the single parameter to the aircrew , the whole homework , the whole factory; Control and control from the appearance of imitating to the computer; Controlling it to optimizing controlling from melting steadily most, mineral processing automation has been already from rudimentary to advanced and becoming more perfect, especially the computer is used in the course to control , guides production practices with the modern theory, competence reaches the new height to automize mineral processing. The automatic control of the flotation course has always been a troubling question, the main reason is complexity of the flotation course and sensitiveness interfered to the course. Flow fluorescence analytical system which offer for studying the online flotation course control system make it possible to succeed in developing in the 1970s. The ones that controlled with the computer were developed successfully with the 1st course, researchers of mineral processing automation develop the ore control system of rubing successfully at first, this succeeds in paving the way for research of the course computer control system of 1st set of flotation of 1976. Over the past 20 years, the researchers of such countries as Finland, Australia , Canada , U.S.A. ,etc. that have still carried on untiring efforts in this field, have made certain achievement. After this, Neuron network, fuzzy logic control, self-adaptation control and expert system, etc. advanced control strategy have applied flotation report that course controls rare to succeed in.Flotation is one of the most important mineral processing methods . The statistics show, 90% of the nonferrous metals mining flotation law treatment. The flotation is still used in the selecting to leave of rare metal , noble metal , ferrous metal , nonmetal raw materials of mineral such as coal extensively. Adding an important link that is the flotation in a production technology of flotation drug, add quantity big or small accurate to influence number , quality , benefit ofproducts directly or not. The traditional artificial regulation way is inaccurate in time either. And the automatic application with medicine control system of flotation, not only has overcome the artificial shortcoming that regulates , and has reduced the medicine produced in flotation and dawdled , has brought the direct economic benefits for selecting the factory, lightenned post workers' labour intensity at the same time.This subject is to such questions as control, management which selects flotation procedure medicine system in the MIDI titanium-processing mill of group of Panzhihua Iron and Steel Co. , using MCGS configuration software to control the configuration. Thesis catch to Panzhihua - Xichang area vanadium mineral processing characteristic , titanium of magnetic iron ore ilmenite mineral processing technology introduce the simple one originally at first, and has added the medicine control system and carried on detailed exposition from such respects as sensor , data gathering , data processing , executive body ,etc. to flotation. The groundwork of this subject is to use MCGS configuration software to selecting the MIDI titanium-processing mill's flotation procedure medicine system to carry on the configuration, which is added to realize the drug computer control.The MIDI titanium-processing mill divide and elect sulphurate the mineral before flotation ilmenite. Sulphide flotation adopts the drug system of routine flotation, namely in order to catch and accept the pharmaceutical with the yellow medicine, pharmaceutical in order to bubble of oil "No. 98. The sulphuric acid is adjusted dose for pH. Catch and accept the pharmaceutical, sulphuric acid to produce flotation ilmenite for the adjustment pharmaceutical of pH with MOS. drug to add and control the configuration system of the MIDI titanium-processing mill, include controlling the main interface mainly, keep drug case control interface, drug is it control window , procedure and sensor interface, hydrogen ion index and PH real-time and history curve window.
