More information
Kemindo started in 2010 with chemicals, beginning with bentonite and lime products. Chemicals are still our main business.
Our customers are paper mills, gold, copper and nickel mines, alumina smelters and general industry.
In 2014 we completed our hydrated lime plant at Labuan Uki, North Sulawesi. It is run by PT Kemindo Cao Resources, uses Italian technology and produces 10 tonnes per hour. It serves gold mines in eastern Indonesia.
The machines are European-made and fully automatic, with about 30 people working inside the plant. It is close to gold mines. Besides hydrated lime, the plant also makes quick lime (CaO).
Besides products, we offer consignment stock, a dedicated warehouse near the customer, technical service on site and tailor-made formulation. See the Services page.
We also supply mining consumables, such as grinding balls and low cement castables. Our other mining services are in the Mining Solutions line.
We are customer-oriented and committed to continuous improvement in satisfying our customers. We keep developing more chemicals for various industries.
