Bauxite, in central Guizhou, is predominantly karst bauxite, but there insufficient research on the effect of paleogeomorphology bauxite development. Xiaoyuan also a and high- low-iron deposits exist study area. This conducts geological modeling using controlled-source audio-frequency magnetotelluric (CSAMT) data drill core data. The effects deposition mineralization are evaluated by assessing ...

In recent years, the rapid development of domestic alumina industry has greatly accelerated consumption high-alumina–silica-ratio bauxite resources in China. The an efficient and clean utilization technology applicable to low-grade China is not only a requirement for resource environmental protection, but also powerful guarantee maintain sustainable China’s aluminum industry. Based on this, aut...

Ivory Coast is a country rich in base metals and precious minerals: gold, manganese, diamond, iron, bauxite, cobalt nickel. These natural resources are exposed to destruction fragmentation by mining activities. The artisanal small-scale exploitation of gold increasingly practiced our rural areas. activities escape often the control monitoring administration. In order better constrain these on e...

The access of Virtual Organizations to raw materials normally requires external resources. In many cases, the market for raw materials is regulated and the VO principles of trust, customer orientation etc. are not applicable. In consequence, the VO needs to provide reliable solutions for the customer while being dependent on the access to the required raw materials. The objective of the propose...

Introduction The extraction of alumina from bauxite by the Bayer process produces a slurry by-product referred to as ‘bauxite residue’ or ‘red mud’. The liquid component of the slurry is highly alkaline and requires neutralisation to render it environmentally benign. A common practice is neutralisation using Mg rich seawater, which results in the formation of the layered double hydroxide (LDH) ...
