Blasting To Improve Fragmentation In Mines

The fragmentation of rock is fundamental to mining. It is the first preparatory stage in the extraction process – making rock small enough and loose enough to be efficiently excavated. But this simple statement underestimates how important this activity is for the whole mining operation. By optimising rock fragmentation by blasting, you can achieve significant improvements in waste productivity, mill throughput, fragmentation.

Role of data to optimize Gold Operations. Data is a key enabler for digital transformation. Mining is data rich with many modern equipments, and processes all creating multiple data points in real-time. In a gold operation, understanding the grade, throughput, recovery and asset effectiveness need to be put into perspective in various time.
