Application of ANN BP model based on principal component analysis method and in mineral processing plant

The best compounding of grade and recovery of concentrate was found through analysis of mineral processing data using box line diagram of exploratory data analyzing method, which were inputted to the ANN BP model based on principal component analysis method to find the more reasonable dosage of reagents at the condition of best compounding, then the dosage can be validated in practical producing and used to gain higher grade and recovery of concentrate.
