    In the condensation unit of the National Iranian Copper Company, a flotation operation is carried out to improve the copper concentrate. In this operation, by adding a substance called lacquer and blowing high pressure air into the mills, the pH of the concentrate is reached to an optimal level of 11.5 to 12.5. Obviously, if the pH of the concentrate output from the mill is outside this range, copper perforation has failed and the concentrate is known as waste. Therefore, one of the most important operations in copper perforation is floatation. At present, there are pipes for drainage of lacquer and blowing of compressed air into the condensing mills, with the discharge amount monitored through the control room. The control room controls these concentrations based on the pH characteristic of the concentrate pH contained in the mill and lowers or increases the amount of lime and compressed air. Problems such as high precision, user control room, and the need for a lot of manpower will make it a way to replace the robot with a human. From the direction of operation, the addition of lighter and compressed air is controlled by the electrical keys, and also the pH of the concentrate present in the mill is also displayed on a monitor. This paper presents an idea for using a robot instead of human control, which makes the robot control the copper flotation control by flexing the arms. The robot presented in this article is simulated by Webots software and simulation results are presented with this article.

    Today, with the advancement of technology, most of the work done in the past by human hands is simulated by robots. Humanoid robots endure the difficult conditions of the work environment and can perform operations better than humans without any errors. Welding robots at high altitudes perform well welding operations. The control robots of the melting furnaces do the correct operation of the furnace control, and so on. In this paper, a robot is designed to control the dump of the mine tracks of the Copper Complex, Shahrbabak, in place of the man-controller, which has the capability to record tracks on the basis of their vehicle identification numbers. The recording by these robots eliminates the data recording errors, and there are no environmental conditions or factors that can reduce the efficiency. Since it can instantaneously store information about the trailer dump traffic in the server's database, it allows the server to prepare reports online for mining experts. In this research, suggestions are made to improve the security and reliability of the project.

    The grinding of materials has long been of human interest. Man has to crush or crush some materials. In the industry, crushing the material is very important. In some industries, along with crushing of materials, other characteristics such as geometric shape and fine-grained dimensions are introduced. Many machines have been designed and made to grind and polish materials of any size to a geometric shape. Despite the high reliability of these devices, there are also advanced laboratories to check the output of these devices. An experiment on microscopic particles causes much time and money. The thesis is based on a three-piece machine, which has a micro-grinding ability of 20 microns in size, and then polishing twentymicron materials in spherical geometric shapes and then grinding materials. Materials that fail to pass through are returned to the mill. This ensures that the quality of the fine-grained material can be removed from the machine. Also, in designing this device, considering the capacity of the screen and the speed of operation, the maximum has been attempted to increase the tonnage acceptable to the device. At the end of this research, the model of the proposed model is drawn up in the Solid Works simulation software, and the dimensions of the device are presented.
