We supply reagents, mining consumables and technical support to the paper, gold mining, alumina smelter and nickel mining industries. - Since: 2010 Kemindo was established on the chemicals business, with bentonite and lime series products as its starting point. The main industries we serve are the paper industry, gold mines, alumina smelters and the nickel mining industry, as well as general chemicals. In 2014 we completed our first hydrated lime plant in North Sulawesi to serve gold mines in the East Indonesia region. The plant is operated by PT Kemindo Cao Resources, uses Italian technology and produces 10 tons per hour. Besides chemicals, we also developed consumable parts for mining such as grinding balls and low cement castables. We are a customer-oriented company committed to continuous improvement in satisfying our customers, and we keep developing more chemicals for various industries. ## Services - **Paper Chemicals**: Pulp chemicals (defoamer, digester additives, enzymes, sodium hydroxide, sulphuric acid, quick lime and lime derivatives, PAC), functional paper chemicals (ASA, surface size, OBA, wet strength, dry strength, native starch, colorants), process chemicals (retention bentonite StarLITE, special bentonite StarSORB PNP, bulky agent StarBULK, micropolymer StarMPOL, retention aids StarPOL), coating chemicals (colorants, OBA, latex, calcined clay) and water treatment chemicals (PAC, polymer, aluminium sulphate, activated carbon, scale inhibitor, defoamer, coagulant, isothiazolin, STPP, citric acid, EDTA, TSP). - **Mining Chemicals**: We support our customers in achieving higher productivity with technical knowledge, chemicals, grinding balls and more. Major reagents we supply include hydrated lime, SMBS, copper sulphate, caustic soda (pearl, flake and liquid), PAC, aluminium sulphate, HCl, activated carbon, xanthates, polymer, CMC, citric acid, castables and grinding balls. Starting with gold chemicals, we now also supply chemicals and consumables for the alumina and nickel industries. - **Others**: Civil engineering (bentonite and polymer) and commodity chemicals (soda, HCl and others). ## Chemicals & Consumables products - [Hydrated Lime](https://site.kemindogroup.com/en/products/hydrated-lime): High-purity hydrated lime Ca(OH)₂ with low impurity levels for water treatment, mining, construction and environmental applications.
