Tunisia says it’s on track to restore once economically crucial phosphate output to levels approaching those before the 2011 Arab Spring uprising, as its beleaguered state-owned miner undergoes a shakeup. Output will probably be at least 4.1-million tons in 2019, up from 2.8-million tons the previous year, Industry Minister Slim Feriani said. Before the revolt that unseated President Zine El Abidine Ben Ali and sparked long-running labour unrest, Tunisia was one of the world’s largest producers of the fertilizer component, creating as much as 8.2-million tons per year.
