Many things led to the closing of the mines. Beginning in 1975, various labor laws were passed but the main reason was that Sicily, due to the different conformation and composition of the sulfur deposits, could no longer be competitive with the mining process used in the U.S. which drastically lowered the cost of extraction.

So, the current mining practice, especially for sulfur is rather slow and therefore quite expensive. The proposed multi-purpose offshore mining system (MOMS) for sulfur recovery emphasizes deployment of solar-power panels aboard a drillship and keeps the principle of Frasch process virtually intact.

This article describes the project of building an $850 million offshore complex in the Gulf of Mexico for producing natural gas, crude oil, and molten sulfur. The Main Pass Mine project was begun in 1992, a joint venture of Freeport-McMoRan Resource Partners (FRP), the mine owner, and Homestake Mining Company. Unique technical challenges were …

At the same time, Freeport's research center developed several technological advances, some resulting in lower mining production costs. In 1952 the company pioneered a process substituting seawater for fresh water in sulfur mining. This process eliminated the need to transport fresh water to sites located near sources of seawater.

Why Is Sulfide Mining Dangerous? If sulfide ore or sulfide tailings are exposed to water and air during mining, a chemical reaction creates sulfuric acid – basically battery acid. There has never been a sulfide mine that has not polluted nearby water resources. Pollution from sulfide mining is very expensive to fix, and a burden for taxpayers.
