Coal

Indonesia is one of the main players in the global coal market and currently the world’s largest thermal coal exporting country. The government of Indonesia has accelerated the operation of new coal mines in response to both local and global demand for coal products which continues to grow. Coal is likely to remain the most affordable fuel for power generation around the world for several decades. The new Clean Coal Technologies are expected to be extensively in operation in near future to minimize the environmental impact of the use of coal.

Commodities & Energy Resources (CER)’s associates currently owns several large coal concessions in Central and East Kalimantan. CER has many long term off-take contracts with medium and large scale suppliers. It has a large, experienced and skilled workforce (more than 150 strong) who strive day and night to ensure that QUALITY and SCHEDULES are always maintained. We continuously monitor the coal during production, hauling, stockpiling, crushing, loading on to the barges and finally loading on to the mothervessel. We have a fleet of more than 100 dedicated barges which ply throughout the year to transport our product thus ensuring timely delivery.

Quartz Sand

PT.MAHAKARYA PUTRA MANDIRI we are one of the best trading company of various kinds of mining quartz sand.

Sand is one very important ingredient in development activities be it a house, building or other buildings. To embed the bricks one brick to another, we need a species, and in the mix of species there are two important components, namely sand and cement. In addition to the building and its interior, sand is also urgently needed in the process of pavement. Either using concrete, paving, or also the asphalt, all using sand as the main ingredient.

Silica Sand

Silica sand is one of the most common varieties of sand found in the world. It is used for a wide range of applications. Sand is the general term for broken down granules of minerals or rocks, technically between about one-sixteenth of a millimeter to two millimeters in diameter, falling between silt and gravel in the spectrum of sizes. There are many varieties of sand in the world, each with their own unique composition and qualities.

Silica is another name for silicon dioxide, SiO2, of which quartz is a specific latticed structure. So silica sand is quartz that over the years, through the work of water and wind, has been broken down into tiny granules. These granules can be used for many different purposes, and can be found in most non-tropical regions of the world.
