Hecla Mining is a gold, silver and other precious metals mining company based in Coeur d'Alene, Idaho. Founded in 1891, Therefor, the second-largest mining company that produces silver in the country is known as the Silver Valley (Idaho). In 1983 this area was designated as a Superfund site by the Environmental Protection Agency, because of land, water and air contamination resulting from a century of mostly unregulated mining.
History and achievements.
Through buying and selling Hecla mining company to various people, it was incorporated in Washington on July 12, 1899, with Amasa Campbell, Patsy Clark, and John Finch as its official founders. James Toner was the first to file a claim on the Hecla Company on May 5, 1855. Edward Moffit was the first manager who saw that they paid their first dividend and began rebuilding the company. James R Smith was the first president of the company. In 1904, Hecla mining company moved its headquarters from Washington to Idaho. Through years of growth, Hecla mining company managed to be listed in New York Curb Exchange and began sending ore to Bunker Hill Mine and Smelting Complex in 1917. Additionally, in 1920, Hecla acquired Federal Mining & Smelting Co.'s claims near Hecla, including the Tiger-Poorman.
Hecla mining company experienced a fire tragedy in 1923, which put them out of business for almost six months. Burkes business district burnt down, which included Hecla’s surface plant. Through insurance, they bounced back to business and rebuilt Hecla’s plant with concrete and steel. Growth was inevitable in the Hecla mining company. In 1930, they gained control of the Polaris Mine and bought the surrounding property. This was a successful move because Polaris could pay dividends for Hecla for the rest of 1940. Hecla company took advantage of the low season, which the country experienced in the 1930s, and it developed new mines, which included Polaris in the 1940s, Hecla began a tailings mill at Osborn, where they processed over 4 million tons of canyons tailings for the next five years. Consequently, more ore had been discovered in 1946 after deepening the silver summit shaft to 3000feet. In 1955, Hecla became the largest shareholder. With Lester Randall as president, the company rose higher because he reconciled Hecla’s balance sheet and sold its interest in exchange for stock. In 1958, Hecla became the principal owner of lucky Friday silver-lead mines after purchasing its shares. Later on, in 1964, the management merged Lucky Friday and silver-lead mines into Hecla mining company, and this allowed Hecla to trade in the New York Curb Exchange. In 1967, Hecla decided to make the most significant move it has ever made in history and agreed to develop the lakeshore copper mine in Arizona, which was unsuccessful due to the low copper prices. Hecla mining company made a considerable loss as a result because the copper mine was closed eventually.
Over the years, the Hecla mining company continued to grow. In 1979, William Griffith was elected as president of the company. He sank a third shaft at lucky Friday, taking it to 6205 feet at 1983. Hecla also acquired the knob hill gold mine and even the whole of random Friday. In 1982, star morning stopped its operations and shut down. Hecla continued to merge and acquire new mines in the years that followed. Hecla has been soaring higher to date, wherein 2011 it landed an environmental suit under the Superfund statute. In 2017, it had reported the full year 2016 production totaling 17.2 million ounces of silver and 233,929 ounces of gold.

According to Hecla report will help mining of the site exceed behind 2031 when the current cite will reach full exploitation capacity. Hecla also proceed a plan for such an expansion as follows:
This plan suggest a better proclaims a new way of reduction in the tailing footprints. 
Ore processing.
Ore is a natural solid material that contains valuable mineral and metals that can be mined and sold at a profit. The process of ore processing begins with crushing and grinding the ore in to fine powder through the help of a SAG mill. Water is added to form a slurry, where lime is added in to the slurry to leach the gold and silver in to a solution. To remove gold and silver from the solution, carbon is added and is later heated to 600 degrees Celsius to extract gold and silver from the tanks. Pure gold and silver is recovered through a process of rinsing the cathodes, retrieving a muddy sludge and drying it and later heating it to retrieve 99 percent pure gold and silver.
