Scientists Worry: Deep Sea Mining Will Harm the Earth's Ecology "Although commercial exploitation of the bottom of the deep sea may become a reality in the next few years, researchers from Greenpeace Organization recently warned that deep-sea mining exploration could be a deadly blow to an already fragile marine ecosystem and cannot be reversed."

The grinding is achieved by impact, creating coarser particles, pinching or nipping giving smaller particles, and abrasion generating fines. Grinding is often finished with a ball mill, which differs from a SAG mill, as it relies on the steel alone for grinding. A SAG mill may have 10% steel where a ball mill will typically have 30%.

The wear of steel balls in continuously operated grinding mills, used in mineral processing to comminute metalliferous rocks, can be described by a simple population-balance model. This model gives rise to a scalar transport equation with a singular source term for the number density of balls as a function of size and time. Exact solutions to this equation are determined under the assumption ...
