Gold mining in Brazil
The necessity of the Amazon is indisputable, however, abuses of it and its natural resources persist in ways that are detrimental to the rainforest, the surrounding local communities, and the planet. Brazil's illicit gold mining industry began to fully blossom in the 1950s, consequently making the Amazon a focal point for the Brazilian Government. Up until this point, the traditional means of Mining in Brazil is centered on the extraction of iron (the second largest global iron ore exporter), copper, gold, aluminum (bauxite-one of the 5 biggest world's productors), manganese (one of the 5 biggest world's productors), tin (one of the biggest world's productors), niobium (concentrates 98% of the known niobium reserves in the world), and nickel. About gemstones, Brazil is the world's largest producer of amethyst, topaz, agate and is a big producer of tourmaline, emerald, aquamarine, Mining in Brazil

Sensor-Based Ore Sorting Technology in Mining—Past, Present
Graphical Abstract. 1. Introduction. Sensor-based ore sorting is gaining increased attention both within and outside the mining industry, as it is leaving the state of pilot plant scale and technology road-mapping, and an increasing amount of equipment is installed in high-capacity production scale environments.Crushing plant design should accordingly provide for laydown and workspace for onsite equipment refurbishment and repair. Where possible, equipment manufacturers should be encouraged to stock and provide spare parts close to the mining operation. Good geotechnical information is essential to crushing plant siting and design. Installing aCrushing Plant Design and Layout Considerations 911 Metallurgist

Treatment And Utilization Of Gold Mine Tailings
What Are Gold Tailings To be shortly saying, tailings are ground up rock minus the gold. The placer or rocks mined from underground which contains gold is called ore. The gold mining process involves crushing the ore into sand and dust to liberate and recover the gold. What’s leftover is called tailings.

Tantalum mining technique blasting, crushing, transporting tantalite ore
Most tantalum mines are open pit whereas some are underground. The mining process involves blasting, crushing and transporting the tantalite ore to start the process of separating tantalum. The ore is then concentrated at or near the mine site, to increase the weight of tantalum oxide and niobium after which the material is concentrated throughMining is an activity that has had a considerable impact on the history of Brazil, whether from an economic, political, social, geographic, or demographic, artistic, and religious point of view.
