Will local Kenyans benefit from lucrative coltan mining?

In January, the Kenyan government announced the discovery of coltan deposits in six counties across the country. This highly valuable mineral is used to manufacture high-tech devices like electric car batteries and mobile phones. The discovery of coltan could place Kenya on the map as a coltan exporter, a sector currently dominated by DR Congo. It is also expected to create jobs in an underdeveloped part of the country.
