Dangote’s $20bn refinery success built on 6 costly business failures

Aliko Dangote, Africa’s richest man, is now worth an estimated $51.3 billion. His $20 billion refinery in Nigeria, which processes 700,000 barrels of oil per day, has become a symbol of African industrial ambition. But the road to that success was paved with setbacks, closures, and tough lessons.

Dangote’s journey shows that even the most successful entrepreneurs stumble. From textiles to telecoms, he launched ventures that failed, sold, or were shut down. Here are six of the most notable business failures that shaped his path to building Africa’s largest refinery.

Textiles: the biggest mistake of his career

Dangote has openly called his textile investment his biggest business mistake. He poured billions into Dangote General Textile Mills and Nigerian Textile Mills, a company founded in 1960 under Chief Obafemi Awolowo. But cheap imports, unreliable electricity, and stiff competition from Chinese and Indian products made the factories unsustainable.

“My biggest business mistake was textiles,” Dangote said. The closures hit nearly 8,000 workers hard, including 6,920 employees at the Ikeja plant. Many had worked there for 25 to 30 years, leaving the company with heavy pension and gratuity costs.

Flour business: two exits, one tough lesson

Dangote Flour Mills, set up in 1999 and listed in 2008, also proved difficult. In 2012, he sold a 65% stake to South Africa’s Tiger Brands for about $200 million. When Tiger Brands struggled and left, Dangote bought the business back at a lower price. Then, in 2019, he exited flour again, selling to Olam for ₦120 billion, citing foreign-exchange challenges.

Telecoms licence: a missed opportunity

Dangote once aimed to challenge MTN, Glo, and Airtel in Nigeria’s telecoms market. He reportedly paid about $20 million for a licence. But internal disagreements, regulatory delays, and the huge cost of building a national network stopped the project. He abandoned the venture, missing out on one of Nigeria’s fastest-growing industries.

Tomato factory: a supply chain struggle

In 2016, Dangote opened a tomato-processing plant in Kano with capacity for 1,200 tonnes of fresh tomatoes daily. The goal was to cut Nigeria’s reliance on imported tomato paste and support local farmers. But the plant kept closing due to inadequate supplies and high operating costs. By 2021, farmers were supplying only about 20% of its capacity, and profits were minimal.

Aviation: a short-lived ambition

In 2002, Dangote launched Executive Jets Services with partners, starting VIP charter operations with a nine-seat Hawker Siddeley aircraft. The plan was to expand into passenger services. But operational difficulties made the aviation venture short-lived.

Liberty Bank: sold to settle workers

Dangote sold Liberty Merchant Bank for ₦1.2 billion to meet obligations from the textile closures. “By the time we sold Liberty, I cashed out N1.2 billion,” he said. “The industry consumed N985 million to pay pensions and gratuities just to get out of the business.”

Dangote admitted the group had “burnt our fingers.” Yet these failures taught him resilience and focus. Today, his refinery stands as proof that setbacks can be stepping stones to global success.

Why Dangote’s story matters for African entrepreneurs

Dangote’s journey offers a powerful lesson for business owners across Africa: failure is not the end. His ability to pivot, cut losses, and double down on what works is a blueprint for resilience. For Ghanaian entrepreneurs and the diaspora looking to invest, his story shows that big wins often come after big risks and tough lessons.
