Cone-Shaped Tailings Dam Storage Technique
Tailings, also known as mine dumps, slimes, tails, reject, and discard tailings, are the materials left over after the process of separating the valuable fraction of an ore from the uneconomic fraction. These materials, consisting of various mineral part......
stope pressure
Air pollution has been increasing in many urban areas, leading to the rise of environmental pollution in some areas. As a result, people are increasingly concerned about air quality and the numerous health problems that result from it. In response to this, one of the ways people have been combatin......
tailings dam
Tailings dams are structures built to contain the waste created by mining operations. Tailings dams are typically constructed by mining companies to hold the by-products of mining ore, such as sand, rock, gravel, and metals. These by-products are referred to as “tailings”, and can be both hazard......
