Aug 30, 2019· Hycroft Mining Corporation is currently in the final phases of proving a largescale innovative twostage sulfur ore oxidation process without the traditional method of using a mill, thus eliminating the need for hundreds of millions of dollars in capital to sustain the production of mining gold and silver at the mine near Winnemucca.
Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (ndida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.

At the beginning of the 1900s, the Frasch process of mining sulfur became the most popular way of extracting it. However, by the end of the 1900s, most sulfur has been manufactured by recovering it from petroleum and gas. The Frasch process is a way of harvesting deep lying sulphur from the ground that was developed by chemist Herman Frasch.
Frasch process, method of mining deeplying sulfur invented by the Germanborn American chemist Herman Frasch. The process involves superheating water to about 170 °C (340 °F) and forcing it into the deposit in order to melt the sulfur (melting point of about 115 °C, or 240 °F), which is lifted to

From the late 1800s to the end of the 20th century, the Frasch process of sulfur mining was commonly used. During the latter part of the 20th century, mining or recovering sulfur as a byproduct of natural gas production or oil refinement became more significant.
The second Fraschprocess mine opened in 1912 in Brazoria County, Texas. The Gulf Coast came to dominate world sulfur production in the early and middle 20th century. However, starting in the 1970s, byproduct sulfur recovery from oil and natural gas lowered the price of sulfur and drove many Fraschprocess mines out of business.
By value of annual production, sulfur is the state''s fourth ranking mineral and accounts annually for about 3 percent of its total mineral production value. Texas at times has produced more than 90 percent of the nation''s sulfur. In 1954 Texas sulfur production by the Frasch process amounted to 3,450,000 long tons valued at 75,100,000.
