Case Studies in Base Metal Processing and Beneficiation: Lessons from East Asia and the SADC Region

The report analyzes base metal beneficiation in Mozambique, Namibia, Botswana, and Zambia, comparing their outcomes with the successful industrial policies of Japan and China. It argues that China's state-led expansion of smelting and refining capacity has caused a 'Great Compression' of margins, making autonomous beneficiation in Africa commercially unattractive. The study concludes that African countries can only succeed in beneficiation through comprehensive industrial policies and strategic partnerships, particularly with Chinese state-owned enterprises.

• China's industrial policy on beneficiation has led to a 'Great Compression' in smelting, refining, and semi-fabricate margins since 2004–05, resulting in subsidized over-capacity that makes beneficiation in Africa commercially unattractive.
• Japan achieved a comparative advantage in refined copper production despite having no domestic copper mines by using industrial policies to provide low-cost inputs for its automobile, shipping, and steel sectors.
• Chinese state-owned enterprises (SOEs) have been the primary drivers of the country's copper refining expansion, constituting approximately 74% of total refinery capacity in 2012.
• The Mozal project in Mozambique successfully diversified the country's export base, with aluminium accounting for 42% of total exports in 2011, but it remains an economic enclave with limited backward and no forward linkages.
• Namibia's Tsumeb smelter operates as a 'smelter of choice' for European producers by processing high-arsenic copper concentrates that are banned in the EU for health and environmental reasons.
• The Namzinc refinery in Namibia achieved commercial viability through high-grade ore (11.6% head grade) and access to cheap electricity from South Africa's Eskom, priced at approximately $0.02 per kWh.
• Botswana's BCL project suffered long-term financial failure due to a high debt-equity ratio that peaked at 39:1, which prevented the company from investing in downstream processing.
• The Tati Nickel Activox refinery project in Botswana was terminated by Norilsk in 2008, allegedly due to a 300% increase in capital expenditure (CAPEX), though the report suggests the technology may have been repatriated to Russia.
• Zambia has the most advanced beneficiation in the SADC region, producing semi-fabricates through ZAMEFA, but it has seen a trend of 'de-industrialisation' as companies shifted toward exporting copper concentrate due to declining refining margins.
• The report argues that base metal beneficiation in Africa is unlikely to succeed without active assistance from China to integrate African producers into the Chinese value chain.
