It is essential to develop a leaching procedure that uses minimal acid consumption, is economical, recovers large amounts of metal, and has a minimal negative impact on the environment. In this paper, a viable hydrometallurgical method using acetic acid as a leachant is suggested for recovering critical metals from waste...

Operando measurements are indispensable here. If we looked at the battery before and after the first charge-discharge cycle, we would see no defects. But during the operation, we see how the defects form and self-heal, leaving detectable scars behind.Andrej Singer, Cornell UniversitySodium-ion batteries have been touted as a sustainable alternative...

Although the mining and metallurgical sectors are still seen as environmentally unfriendly industries, innovation in these sectors has been increasing since the beginning of the century, including in the development of green technologies. Four years ago, the World Intellectual Property Organization (WIPO) released a study measuring innovation in the mining...

With a grant from the Office of Naval Research, MIT researchers aim to design novel high-performance steels, with potential applications including printed aircraft components and ship hulls....

MONTREAL, Feb. 02, 2023 (GLOBE NEWSWIRE) -- Imperial Mining Group Ltd. ("Imperial") (TSX VENTURE: IPG) (OTCQB: IMPNF) is pleased to announce the filling of patent applications for its two-stage hydrometallurgical methods and processes for the extraction of scandium (Sc) and rare earth elements (REE) from Crater Lake project mineralization....

It is generally conceded by flotation men that the condition at the surface of a particle of mineral or gangue is the most important factor controlling its behaviour in a flotation cell. Much research work has been devoted to the study of the forces that are active at the surface...

Microscope images showing the path of a fracture and accompanying crystal structure deformation in the CrCoNi alloy at nanometer scale during stress testing at 20K (-424°F). The fracture is propagating from left to right. Image: Robert Ritchie/Berkeley Lab.Scientists have measured the highest toughness ever recorded, of any material, while investigating...

In the examination of an undeveloped prospect a decision must be arrived at from an inspection of the outcrops and the exposures in a few shallow pits. Prospects that are offered for sale rarely expose any important quantity of good ore, work having usually been stopped when the immediate exploration...

In approaching the subject of diamond-drilling practice, a brief history of the origin and development of the diamond drill may be of interest. The use of black diamonds for boring holes in rock was discovered in 1863 by Rudolph Leschot, a French engineer. In 1864, he employed a diamond bit...
