Geometallurgy—A Route to More Resilient Mine Operations

Geometallurgy is an important addition to any evaluation project or mining operation. As an integrated approach, it establishes 3D models which enable the optimisation of net present value and effective orebody management, while minimising technical and operational risk to ultimately provide more resilient operations. Critically, In 1911, the Itabira Iron Ore Co. had been established with American capital to develop huge iron ore reserves in Minas Gerais and was granted an exclusive right to develop an export railroad to the coast (the current EFVM) in exchange for a commitment to build a steel mill. Mining in Brazil experienced a new surge because of the priorityHistória da mineração Brasileira (mining history of Brazil)

Mineral Processing an overview ScienceDirect Topics

12.7 Ore to Concentrate and Metal. Mineral processing or mineral beneficiation or upgradation involves handling of three primary types of ROM ore material which has been blasted, fragmented and brought out from in situ position. These materials can be used directly or by simple or complex processing and even applying extractive metallurgy likeOnce the metalliferous ore,coal, industrial mineral s or mineral fuels are mined, they are processed to extract the valuable commodity. In contrast, mining wastes are placed in large heaps on the mining lease. Nearly all mining operations generate mining wastes, often in very large amounts.

Ore Mining, An Introduction on SpringerLink

Due to the long-term underdevelopment of rock drilling and mine blasting technique in China, manual labor was still used in mining, drilling, ore handling, etc. In 1556, Georgius Agricola, a German scientist, published the book De Re Metallica, which was the first comprehensive work on mining and metallurgy technology in Europe.Fig. 1 illustrates the simplified supply chain starting at the mine and ending at the concentrate loadout. Crushed ore is currently hauled to the ore storage facility via an Automated Train Operation system (ATO). In order to increase the production rate, the construction of a 6 km overland conveyor (Parallel Ore Delivery System or PODS), and Ore storage simulation for planning a concentrator expansion
