Brief History of Mining Advancement of Mining

In today's technologically-advanced society, mining techniques are always improving. For example, using surface mining techniques, many mining operations are now able to extract over 85 percent of minerals and 98 percent of metallic ores — without digging a shaft or endangering the lives of workers.

Mining Valuation Techniques

The best way to value a mining asset or company is to build a discounted cash flow (DCF) model that takes into account a mining plan produced in a technical report (like a Feasibility Study). Without such a study available, one has to resort to more crude metrics. Here is an overview of the main valuation methods used in the industry:

Iron Ore Mining

MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.
