The global silver trade between the Americas, Europe and China from the sixteenth to nineteenth centuries was a spillover of the Columbian Exchange which had a profound effect on the world economy. In fact, many scholars consider the silver trade to mark the beginning of a genuinely global economy, with one historian noting that silver "went round the world and made the world go round."

Silver mining companies are constantly trying to reduce their costs in order to generate FCF. Hecla Mining (HL) delivered free cash flow of $44.5 million in 2016, which represents growth of 243%.
The project consisted of a conventional open-pit (24,000 tonnes per day) mining operation, with a pressure oxidation / carbon-in-leach (CIL) plant to recover gold and silver, as well as a copper sulfide precipitation circuit to recover copper. Fluor staff peaked at 380 in March 2011, and contractors peaked at 7,800 for 3 months in April 2011.
