Simandou, Nimba and Zogota: the long and difficult road …
Running story Simandou, Nimba and Zogota: the long and difficult road to the start of iron ore production Guinea, which has some of the biggest unexploited iron ore deposits in the world in its south eastern corner, is also one of the countries in which they are the most difficult to bring into production, principally because of the absence of infrastructures to evacuate the ore.
Mining
Most iron ore mining operations use the 'open pit' method, where miners drill into the rock and blast the ore-bearing material loose with explosives. Huge excavators are then used to gather the loosened ore.
20 Pros And Cons Of Open Pit Mining
By removing the surface layers of rock and soil, open pit mining provides access to vast quantities of ore that would otherwise remain untapped. This makes it an ideal method for mining projects that require large-scale extraction.
Open-Pit Mining: A Comprehensive Guide
Open-pit mining, or opencast mining, is a surface mining technique used for large-scale operations. It involves extracting minerals from a pit by removing waste rock and overburden. Commonly used for minerals like copper, gold, and iron ore, requires heavy equipment such as trucks and shovels to efficiently extract the ore.

Open-Pit Mining | Method and Process
Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. This surface mining technique is used when mineral or ore deposits are found relatively close to the surface.
Open Pit Mining
Open pit mining is considered different from quarrying in the sense that it selectively extracts ore rather than an aggregate or a dimensional stone product. Open pit mining is applied to disseminated ore bodies or steeply dipping veins or seams where the mining advance is toward increasing depths.
