Investment Prospects in People's Former Mining Areas

 

Mining activities in Indonesia have been going on for a long time, more than a thousand years. Beginning with the arrival of immigrants from China who mined gold in several areas, continued in the Hindu era, the Dutch occupation, and Japan. Mining activities in addition to mining businesses use high-tech equipment, many small-scale mining companies also use simple equipment with a very limited capacity.

The long period of mining activities in many areas has left mining marks due to various backgrounds or reasons. This mining activity ends not only due to the depletion of resources or reserves of excavated materials being cultivated, but also due to limitations in technology, social aspects, and capital. This can cause mining activities to stop so that it is possible for minerals to be left behind in ex-mining areas that still have the opportunity to be utilized.

The ups and downs of mining business activities have caused ex-mining areas that are often found in some areas to still contain mineral commodities that have the potential to be cultivated. In addition, the development of mining and processing technology, changes in market prices, as well as the need for certain commodities that previously had no economic value at all, have caused the excavation material left behind in ex-mining areas that were previously uneconomical to be cultivated to become economically potential for development.

The distribution of community mining activities that can be found in almost all parts of Indonesia with very limited capacity of mining and processing facilities has the potential to leave minerals that are not accessible to the mining/excavation process, as well as low processing yields, and the tailings produced tend to still contain minerals. valuable.

Excavated materials left in ex-mining areas can be in the form of the same commodities that were cultivated when the mine was still active, or in the form of associated minerals, and other excavated materials which at the time the mine was still active had not been cultivated. Exploitation of excavated materials in ex-mining areas can be done by reusing existing infrastructure, such as tunnels and other supporting infrastructure. Tailings in ex-people's mining areas are generally still left on the surface without any reclamation efforts covering them with soil and plants, so that tailings reprocessing can be carried out without the overburden stripping process.

Some ex-mining areas still have the potential to be developed for leftover minerals. Empowerment of left-behind minerals in ex-mining areas, in line with conservation principles in an effort to obtain optimal benefits from potential which exists.
