Gold in the Philippines: How is it extracted

gold mining operation in the philippines

When we talked the last time about gold in the Philippines and why foreign settlers who loves gold choses to settle in this country, I thought of expounding more idea about this topic.

It is also for some people’s awareness that they should understand where gold in the Philippines are extracted from.

Basically, natural gold in the Philippines comes from highly-mineralized soil and that means you will not just find gold minerals in the soil but also other solid elements such as silver, ore, aluminum, etc.


In the norms, gold are extracted in volume through the process of mining.  Mining operation may come in a way of digging holes into the deeper part of the ground, and once the tested soil becomes positive with the characteristics of gold presence, the soil is transferred to a soil storage area before relayed to a conveyor in its way to a ball mill.

The ball mill crushes hard soils and rocks (pulverization) into smaller bits until it becomes almost 96% crushed.  By this process, the gold may have already come out and separated from its holder soil or rock.  This gold comes down to a strainer and separates from the rock and soil.  The rock and soil will go further for more grinding process until completely powdered and those extracted will be collected for drying, split into fractions for sampling, analysis and further going into assay process.

Assay process is where the potential gold and silver bearing solid is being melted and treated with chemical to properly identify accurately how the metal (gold or silver) may be valuable bring out its best quality or grade and to understand its value.

Assay process has been present since about 500 years ago and the most common is the fire assay.  At the current times however, there are more advance assay process equipment that are being use by advance operation mining companies such as atomic absorption, mass spectroscopy and other advance techniques.

I will not discuss further in details what is being done in the whole process but it basically goes like what has been mentioned above: the Philippines gold mining process in layman terms.

On the other hand, some mining operations extract the soil directly by scraping the ground.  This may be look upon as almost the same as quarrying operations where the scraped soil is also transferred to a soil storage area before going to the milling process.

But there is more to this, Gold Panning is another process where people recovers gold particles from soil which were brought by erosion and flowed into rivers and streams.  Some people who are into gold panning uses a pan to separate river soil and the gold particle apart.  Though this may not be a big extraction operation, this is also an awesome money maker to many.


Gold extraction in the Philippines takes a lot of process and takes the Philippine gold price into the next level.

I may be discussing the process further in my next article but meantime, those process mentioned above are the basics of extracting natural gold in the Philippines.
