In October 1943, Alcan incorporated Jamaica Bauxites Limited to investigate Jamaica’s bauxite as a potential aluminum ore. Early test shipments to the United States helped confirm the ore could be processed using the Bayer process (a common method for turning bauxite into alumina). This marked the start of Jamaica’s modern bauxite-alumina industry story.
In 1952, Reynolds Jamaica Mines began exporting bauxite for commercial purposes, with early shipments leaving from Ocho Rios. This shift from exploration to commercial export established bauxite as a major new pillar of Jamaica’s external trade. It also set the stage for later growth in alumina refining on the island.
In December 1952, alumina processing began at Kirkvine Works in Manchester. This was a key move up the value chain from exporting raw ore to producing alumina (the intermediate product used to make aluminum metal). It also increased Jamaica’s role in the global aluminum supply chain beyond mining alone.
In 1959, Alcoa established a bauxite venture in Jamaica, strengthening foreign investment in the sector. The operation later exported its first shipment of bauxite in 1963. This helped widen the number of major producers operating in Jamaica, increasing output and global linkages.
In October 1959, alumina was first produced at Ewarton Works in St. Catherine. Adding a second refinery expanded Jamaica’s processing capacity and deepened its specialization in alumina exports. Over time, Ewarton became one of the island’s long-running refining sites.
On May 18, 1969, the Alpart refinery at Nain, St. Elizabeth began operating after major construction efforts. The plant expanded Jamaica’s alumina capacity and anchored a large industrial complex in the south of the island. Its scale also increased the sector’s influence on jobs, infrastructure, and foreign exchange earnings.
In 1972, the venture later known as Jamalco began alumina production at a refinery in Clarendon, exporting alumina through Rocky Point. This further shifted Jamaica toward exporting processed alumina, not only raw bauxite. The site would later become central to state participation through joint-venture ownership.
On June 8, 1974, Jamaica imposed a new bauxite production levy after negotiations with companies failed. The levy was tied to the price of primary aluminum rather than company profit measures, aiming to increase national revenue from a finite resource. This policy became a major turning point in Jamaica’s bargaining position with multinational producers.
On August 19, 1975, Revere announced it was suspending operations at its Maggotty alumina facility, laying off hundreds of workers. The closure followed market pressures and the changed fiscal environment after the levy, illustrating how global aluminum demand and local taxation could quickly affect viability. It also highlighted the risks of dependence on a small number of large industrial employers.
After the 1975 levy negotiations, Jamaica established new institutions to strengthen oversight of the industry, including the Jamaica Bauxite Institute (JBI) (incorporated in October 1975 and established in 1976). JBI’s role included research, monitoring, and technical support for the government’s participation in bauxite and alumina. This built state capacity to manage revenues, contracts, and long-term sector planning.
In early 1984, Reynolds announced it was pulling out of Jamaica, reflecting recession-era pressure and competition from lower-cost bauxite sources. The exit signaled that Jamaica’s industry faced not only domestic policy choices but also a changing global cost landscape. It also foreshadowed broader contractions in the mid-1980s.
In February 1985, Alcoa shut down its Jamaica operations, citing weak global conditions and high costs. The shutdown underscored how global aluminum oversupply could rapidly reduce demand for Jamaican alumina and bauxite. It also increased pressure for new operating arrangements and policy responses to protect jobs and foreign exchange.
In 1988, the Government of Jamaica acquired a 50% share in the operation that became Jamalco, creating a joint venture with Alcoa as managing partner. This reflected a long-running national goal: securing a larger public stake in a strategic export industry. It also changed how profits, risks, and investment decisions were shared between the state and private partners.
In 2009, the global financial crisis sharply reduced alumina demand and prices, leading to major shutdowns. Alpart announced a suspension of operations with a planned May 15, 2009 closure, and Jamaica’s Kirkvine and Ewarton operations also ceased around this period as conditions became unviable. This was one of the industry’s deepest downturns, with large employment and revenue impacts.
After the 2009 closures, Ewarton Works reopened in 2010 while Kirkvine remained mothballed. This reopening showed a partial recovery strategy focused on the most viable assets. It also marked a transition from crisis response toward rebuilding export volumes and operating stability.
In June 2017, Alpart’s refinery reopened under new owner JISCO after being closed since 2009, signaling renewed foreign investment and a bid to restore production capacity. In September 2019, operations were suspended again to carry out upgrading work, showing the ongoing need for modernization in a competitive global market. Together, these events represent the industry’s “rebuild and retool” phase after the 2009 collapse.
On April 25, 2023, Century Aluminum announced an agreement to acquire Noble Group’s 55% interest in Jamalco, a major bauxite-and-alumina joint venture in Jamaica. The change in lead private partner reflected ongoing restructuring in the global commodities and aluminum sectors. By this point, Jamaica’s aluminum-related industry had become a long-running mix of state participation, foreign ownership shifts, and repeated adaptation to global market cycles.
