Home / Business / Resources Division
Resources Division is mainly involved in the quarrying of limestone and the manufacturing of lime products such as quicklime, hydrated lime and quicklime powder. These products are used in a wide range of industries, and are sold domestically as well as exported to various countries around the region.
The history of Rock Chemical Industries (Malaysia) Sdn Berhad (“RCI”) began when Rock Chemical Industries (Malaysia) Sdn Bhd was incorporated in Malaysia under the Companies Act 1965 on 30 January 1973.
RCI diversified into lime products in 1993 and made a significant change in its corporate strategy by selling 60% of its shares in the white cement business in 2000, and the remaining 40% in 2002. RCI today is principally involved in the quarrying of limestone and the manufacturing of lime products. RCI’s lime operation is carried out mainly by RCI Lime Sdn Bhd, a wholly-owned subsidiary of RCI. RCI Lime operates three Chisaki and four Cimprogetti lime kilns, making a total capacity of 1,560 mt/day in Gopeng, State of Perak.
RCI Lime is a leading supplier of quality lime products and is one of the largest producers in Malaysia with operating facilities located in Gopeng.
RCI started its lime business in 1993 by setting up its first Chisaki lime kiln from Japan at its factory in Lahat, with a daily production capacity of 70 mt/day of quicklime. Due to overwhelming demand, a similar second kiln (70 mt/day) and a hydration plant (100 mt/day) were constructed in 1994 and a third kiln added in 1996. To ensure constant limestone supply and consistency in quality, RCI Lime has its own limestone quarry at Gopeng and within its vicinity.
RCI Lime acquired from RCI its lime operation in 1998 under an internal rationalisation exercise to enable RCI Lime to focus on producing high quality calcium lime and value added lime based products.
Limestone is the main raw material for the products of the Resources Division, and all limestone used for the products are sourced from the quarries of the Group located within the vicinity of the manufacturing plants. The Division is actively sourcing and acquiring limestone reserves to secure continuous supply of good quality limestone feedstock in the long-term.
In late 2001, RCI Lime embarked on an expansion plan to install a new state-of-the-art kiln and a hydration plant next to its quarry in Gopeng. The new Cimprogetti lime kiln was commissioned in January 2003 to produce 250 mt/day of quicklime and 8 mt/hour of hydrated lime. The second Cimprogetti lime kiln with the capacity of 300 mt/day was subsequently constructed in early 2005 and completed in February 2006. In the years that followed, RCI Lime strengthened its foothold in the industry by enlarging its markets locally and internationally. The next cycle of RCI’s expansion plans began in the year 2015, with the addition of a third Cimprogetti kiln with a capacity of 420 mt/day of quicklime and a new 15 mt/hour hydration plant which were commissioned in the same year. Along with that, a new petcoke grinding plant and a quicklime grinding plant were also built and commissioned between the years 2015 – 2016.
The fourth Cimprogetti kiln began operation in March 2017 with quicklime capacity of 420 mt/day. With the new added capacity, RCI Lime have a total combined production capacity of 1,560 mt/day of quicklime and 23 mt/hour of hydrated lime thus making RCI Lime one of the largest lime producers in Malaysia. We have in 2018 embarked on the construction of a fifth Cimprogetti kiln with capacity of 420 mt/day of quicklime, which is expected to be commissioned by end of 2018.
RCI Lime has attained the ISO 9001:2015 certification in December 2017. A central laboratory equipped with modern and sophisticated equipment supports and qualifies the quality at Gopeng plants. The laboratory has the capability to conduct research and performance testing for many end user applications of their products.
Quicklime is successfully applied in the steel manufacturing industry, pulp and paper manufacturers, sugar finery, mining and for soil stabilisation in the plantation and construction industry.
Quicklime is produced by the thermal dissociation of limestone. Its principal component is calcium oxide. RCI Lime uses limestone aggregates with size ranges from 20mm to 80mm. Quicklime produced is of high quality with a minimum of 90.5% calcium oxide content.
Hydrated lime is a value-added downstream product of quicklime. It is a fine, dry powder manufactured by treating quicklime with sufficient water to satisfy its chemical affinity for water, thereby converting oxides to hydroxides.
Hydrated lime is used in many industries such as water and waste water treatment, agricultural applications, flue gas desulphurisation and in chemical processing plants. These products are used in many of the same applications as quicklime but hydrated lime is chemically more diluted than quicklime. It is used in industrial applications where controlled sizing is needed or where slakes are not utilised.
Syarikat Cheng Sun Quarry Sdn Bhd is principally involved in the quarrying of limestone for processing into fine calcium carbonate powder. Cheng Sun’s plant and factory are in Keramat Pulai, near Ipoh. The raw material which is high quality limestone, is obtained from an adjoining 9-acre limestone hill belonging to the company. The fine calcium carbonate powder is used as a filler in the paint, shoe, plastic and rubber glove industries.
Batamas’ current core business is in the manufacturing and trading of cement bricks. Quarry dust and cement are the essential raw materials required for the production of the bricks. Cement bricks are used as building materials in the construction industry. The product is marketed in Malaysia using the brand name “Ecco”.
Batamas factory is located on a 10-acre site in Batu Gajah and at Simpang Pulai site. The factory utilises fully automated platinum 7S Korean machinery to produce high quality cement bricks.
In August 1996, Batamas was an associate of RCI but subsequently became a wholly-owned subsidiary in 2007.
