A brief mention of some of these problems is given below1. There is lack of proper policy for the extraction and processing of mineral resources in the country.
Global demand is rising for mineral resources of all kinds, including metals, industrial minerals, and solid fuels like coal. Mineral resources are unequally distributed around the globe, reflecting the vast differences in geology of different parts of the Earth.
The total volume of consumable mineral resources is just 1% of all the minerals present in the earth’s crust. However, the consumption rate is so high that these mineral resources which are nonrenewable will get exhausted very soon. Here are some of the measures to conserve minerals: Use of minerals in a planned and sustainable manner.
Mining regulation is handled by the Ministry of Solid Minerals Development, which oversees the management of all mineral resources. Mining law is codified in the Federal Minerals and Mining Act of 1999. Historically, Nigeria's mining industry was monopolized by stateowned public corporations.

This chapter delivers a mixed forecast for the impact of population growth on mineral resources. On one hand, technological advancement has allowed humans to extract resources from places that previously were impossible to explore. Deepwater resource mining has grown, and estimates of overall resource reserves are continually being adjusted upward.
Geological scarcity of mineral resources must be distinguished from economic scarcity. Economic scarcity of mineral resources is the umbrella concept and can be caused not only by geological scarcity, but also by many other factors. Ultimately, the market price is determined by the balance between demand and supply.
When companies break up materials during mining, the dust can release a variety of heavy metals commonly associated with health problems. As dust, these minerals (such as the asbestoslike mineral riebeckite) can be absorbed into lung tissue, causing problems like pneumoconiosis and silicosis, commonly known as "Black Lung" (Paul Campbell, 2011).
At first glance, sustainability and mineral resource development appear to be in conflict. Mining depletes finite resources and in a strict sense, therefore, is inherently unsustainable. For instance, there is only a finite amount of copper in the earth’s crust, and each unit of copper extracted ...
Feb 01, 2013· The current turbulence in the mining industry in South Africa has its roots in several different factors.

Several developed countries have been exploiting their original mineral resources by using as intermediate goods and finished products. Many of the countries are importing minerals from other countries, refining, value addition and then exporting. Pakistan is endowed with huge reserves of minerals covering an outcrop area of 600,000 sq. Kms.
Mineral resources. Approximately 20,000 Russian mineral deposits have been explored, and more than onethird of these have been mined. The Ministry of Natural Resources cited serious problems in the sector, which included the depletion of reserves and the low discovery rate of new reserves.
During the exploration process, a mining company seeks an area where the desired mineral resource is concentrated and attempts to determine the size of the ore body and the mineral resource's ore grade. Higher ore grades (higher concentrations) make the mining project more viable (see Table 1).
