INTELLIGENT SYSTEM FOR CONTROLLING OPERATIONAL PARAMETERS OF A SMELTING FURNACE
This application addresses an integrated smart system to control the variables involved in the process for melting mineral concentrates. Specifically, it addresses an integrated smart system that allows the whole melting process operation to be controlled, measuring the mineralogical quality and quantity of the concentrate that is injected into the melting furnace, as well as variables such as the temperature, the level of the liquid phases and the percentage of copper within the furnace.
