PT. GREEN GOLD TECHNOLOGY

An Indonesian based company

Mineral project development is a complex, high-risk business. Maximizing the potential of a mineral project requires broad engineering and operations experience.


When exploration, feasibility, construction, and production are treated as isolated areas, opportunities are squandered and capital is wasted. Poor choices in flowsheet design and equipment, together with defective operational concepts at the feasibility stage, can lead to much higher capital and operating costs down the line.


These issues can be prevented by seeing the big picture from the start.
GreenGold offers a fully integrated approach to the management of mineral project development and operations.


We combine operational excellence with world class technologies that are low cost, long term, and environmentally friendly. We understand what it takes to develop, create, and sustain an operation. We have turned around failed businesses and helped create impressive success stories from marginal projects.


New and existing mineral operations are benefiting from GreenGold today. There is room for improvement in the mineral industry. We can do much better – so why not?
