Jackling demonstrated that the mining of low-grade ores, containing only two percent copper, could be economically feasible when mined and processed in mass production. Jackling also utilized new methods of metallurgical extraction, primarily those involving an improved flotation process for the concentrating of low-grade ores.

It further helps businesses to solve more complex problems and make smarter decisions. DM is a potentially powerful tool for companies; however, more research is needed to measure the benefits of DM. If managers are better able to quantify the benefits of DM, they will be in a better position to justify its relatively high costs.
