2011-9-2 4.1 Waste reduction measures like recycling, form the most important aspect of any waste management system. Some progress worth mentioning is ~he open-pit back-fillin~ at Nchanga and the newly-introduced underground mining technology of "cut and fi 11" in Luanshya which could significantly reduce th~ amount of wastes for disposal.

2016-7-31 limestone treatment of acid mine drainages, which renders the acidity neutralization processes ineffective. Based on this observation, limestone is proposed herein as a sorbent for sulphate removal, from neutral mine drainages. Therefore the present work investigated sulphate removal from a pH 6.5 mine water through sorption on limestone.

2020-4-9 Limestone mining can pollute water and create sinkholes. When limestone dissolves while it's still in the ground, caves and gullies form, a natural phenomenon known as karst. Although this doesn't hurt the environment in its natural form, once the limestone is mined out, sinkholes can form and disrupt underground waterways.

The mining industry uses geomembranes for a variety of waste containment systems. Because they are durable, puncture-resistant, and can withstand harsh environmental conditions, chemical solvents, heavy metals, and even radioactive materials, they are ideal for containing mining processes and byproducts. Here Are Four Ways Geomembranes Are Used for Waste Containment Systems in the Mining Industry:
