Resources
Division
Extraction
RCI owns and operates several limestone quarries close to its lime-producing plants. This redundancy ensures a secure supply of kiln feed raw material.
Processing
Limestone extracted from the quarries is washed and screened to achieve optimal sizes and chemical composition, ensuring compliance with product quality standards.
Manufacturing
RCI produces high-purity lime using multiple state-of-the-art lime calcination kilns.
Packaging
RCI is able to deliver lime products in bulk or jumbo bags. Preselected high-quality bags are used to preserve product quality during storage and transportation.
Distribution
RCI’s logistics team works with customers to provide reliable and cost-effective supply chain solutions, ensuring on-time delivery. These solutions include road transportation, port handling, and storage for both sea freight containers and bulk shipments.
- In 1975, RCI commissioned its first plant to produce white portland cement locally, replacing imported white cement. It became the sole white portland cement manufacturer in Malaysia and a significant exporter in the East Asian region.
- On 30 November 1989, RCI transitioned into a public company, adopting the name Rock Chemical Industries (Malaysia) Berhad.
- On 28 June 1990, it was listed on the Second Board of the Kuala Lumpur Stock Exchange (now Bursa Malaysia).
- In 1993, RCI diversified its portfolio by venturing into lime production. It shifted its corporate strategy by selling 60% of its shares in the white cement business in 2000 and the remaining 40% in 2002.
- On 29 June 2012, Rock Chemical Industries (Malaysia) Berhad was privatised and subsequently delisted from Bursa Malaysia.
- On 27 July 2012, RCI became a wholly owned subsidiary of MFCB
Today, RCI is a leading regional lime manufacturer, providing high-quality products to a diverse range of industries across Malaysia and the Asia-Pacific region. Its products – quicklime and hydrated lime – serve various applications, addressing environmental challenges in heavy industries and supporting essential sectors such as food production and potable water treatment.
Lime products are used for the neutralisation of contaminants, waste, and pollutant by-products generated by large heavy industries that are essential to the modern economy, such as steel, paper, and mining. There are no available substitutes for lime products in terms of usage and efficacy.
With access to abundant limestone reserves and state-of-the-art lime kilns, RCI ensures a reliable and sustainable supply for its customers. Strategically located in Malaysia, it benefits from excellent connectivity to international ports, enabling cost-effective distribution. Whether by road, rail, or sea, RCI delivers its products efficiently to its partners.
Quicklime
Quicklime is widely used in the steel manufacturing industry, pulp and paper production, sugar refining, mining, and for soil stabilisation in plantations and construction.
Quicklime is produced by the thermal dissociation of limestone, with calcium oxide as its principal component. RCI Lime uses limestone aggregates ranging in size from 20mm to 80mm. The quicklime produced is of high quality, with a minimum calcium oxide content of 90.5%.
Hydrated Lime
Hydrated lime is a value-added downstream product of quicklime. It is a fine, dry powder produced by treating quicklime with sufficient water to satisfy its chemical affinity, converting oxides into hydroxides.
Hydrated lime is used in various industries, including water and wastewater treatment, agriculture, flue gas desulphurisation, and chemical processing. While it serves many of the same applications as quicklime, hydrated lime is chemically more diluted. It is preferred in industrial applications where controlled particle sizing is required or where slaking is not utilised.
