Gold Cyanidation Plant Dcs Control System Design And Development

As the main step of gold mine smelt, cyaniding craft plays an important role in the whole process. However, the performance of domestic cyaniding craft is not efficient enough, and it hasn't shaped a canonical pattern. Most of the crafts were completed tentatively by skilled workers of these factories. Most of the equipments are operated manually. Because of various equipments, atrocious circumstance, serious disturbance of environment, it is difficult to realize optimal control and to achieve the high craft target. Moreover, the requirements and needs of manufacturing are increased day by day, which is resulted in the augment of the complexity of the field control continuously.With the popularization of the computer, the supervisory system of the computer is going deep into the heart of the people. The computer disposes of a great deal of data fleetly and does a lot of repeated work, however much creationary work such as analyzing, estimating the result and making the decision of these result will be done by manager. This system is the main pattern of using the computer into the management of the enterprise. So, in order to make technical parameter more stable, and the craft more perfect, automatic control of the whole arts and crafts must be done.This paper setting out from an actual problem introduces a automatic control system of cyaniding arts and crafts based on DCS, for an example of Jinchiling gold mining ltd. of ZhaoJin group in Shandong. This system was setted up with the process controlling produces of SIEMENS PCS7, and gather the message of 980 dots. On the base of traditional DCS, the fieldbus was used to this system. The PLC was programmed with SEIMENS STEP7, the senior PC was programmed with SIMATIC WINCC.This system also transmits important data into EXCEL sheets by way of DDE connection of WinCC. The manager can inspect the main craft parameters and workload of operators via this system. The system also gives an important criterion of making use of energy sources.In this paper, the development and design of the automation control system is...
