The genuine need for a solution to carryback in the material handling industry was the primary driving force behind the invention of the 1C Belt Cleaner more than three decades ago. Though belt cleaning systems may be a small part of a mining operation, the ability to eliminate carryback is a critical job. Relief from carryback issues means equipment is spared, work areas are safer and clear
Diamond is recognized as the only material sampling the very deep mantle to depths exceeding 800 km, as shown in figures 25 and 26. Diamond is less useful at revealing deep carbon flux (the amount of carbon in motion) because it can provide only a small, variably distributed sample that is usually not directly related to its kimberlite host.

Gravity tends to make the particles settle, whereas diffusion acts to homogenize them, driving them into regions of smaller concentration. Under the action of gravity, a particle acquires a downward speed of v = μmg, where m is the mass of the particle, g is the acceleration due to gravity, and μ is the particle's mobility in the fluid.
The Mercury Problem in Artisanal Gold Mining. Mercury‐based artisanal and small‐scale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold.
