The Mining Saga: Artisanal and Large-Scale Mining




We hesitate upon hearing the word mining, but do we really understand the depths and meaning of everything that is mining? Why are we quick to judge the things that we do not really understand?

An important classification of the mining industry is between the small scale mining industry and the large-scale metallic industry.

Artisanal and small scale mining is an emerging socio-economic area in developing countries especially for the rural poor. They are subsistence miners, not officially employed by a mining company, and uses their own resources to independently mine or pan gold. They usually work with hand tools. It is estimated around 13 to 20 million men, women and children are directly engaged in small scale mining.

Small scale mining activities may include as simple as panning gold in the river to the complex underground workings and small-scale processing plants. In South Africa, artisanal miners process gold by hand crushing the ore on open rock surface, then the pulverized ore is concentrated using visual sorting, gold panning, sieving and by washing on riffle tables made of plastic sheets on heaps of sand. Final gold extraction is accomplished by mercury amalgamation. Mercury burns off using an oxy-gas torch. According to Gerard Brimo, (President of the Nickel Asia Corporation and the Director of Chamber of Mines) Philippines small scale mining is a big industry as gold valued at almost P43 billion was sold in a “no-name” basis to the Bangko Sentral ng Pilipinas in 2010. As the output from this sector is added to the mineral industry it results to the distortion of the taxes paid against the total revenue.

Large scale mining on the other hand is undertaken by big mining corporations, multinational or local. They employ numerous labour force and employees and they use technologically advanced equipment in a huge area. They mine until there is none left. After the mining activities, they then execute the rehabilitation program. During the mining period, the large scale miners, takes care of the host community in terms of their welfare and safety.

A more stringent guideline is followed by large scale mining. They must file for exploration permit, the Mines and Geosciences Bureau processes their application and check if the area is open for exploration. The large-scale metallic mines occupies about 60, 000 hectares that would only amount to 0.2 percent land mass of the Philippines. There are many exploration applications because the odds of finding a commercially viable deposit are low.

Mineralized lands are not conducive to agriculture. To set an example, laterite is a soil type that is full of iron and some nickel. It is not an agricultural area and cannot be bio-diverse. Because of this type of soil the growth of trees become stunted. Lateritic areas are also prone to soil erosion and siltation when it rains. It also discolour the coastal waters as you can see a red-looking soil which is really iron oxide.

As I delve deeper into mining research, responsible mining can be achieved if we open our eyes and be equally vigilant that mining companies follow the law. The Philippines is positively a country to be reckoned with, in this time and age, we can come into agreement that we should welcome all feasible forms of economic activity to increase the speed of its development.

Next up is an attempt to answer the question what is responsible mining?
