Mining in Ecuador

Mining in Ecuador played a small role in the Ecuadorian economy
in the 1980s, contributing only 0.7 percent to the GDP in 1986 and employing about 7,000 persons. Inaccessibility of the regions where minerals were located and the incomplete exploration of resources hampered mining activities. Although observers believed that Ecuador had reserves of gold

the latter dominated the industry. Miners generally produced limestone in many small operations countrywide and used it in local cement plants.
Gold
, largely forgotten since its early exploitation in the sixteenth century, grew in importance in the 1980s; by 1987 Ecuador was exporting 2.4 tons per year. The southern Sierra region held the country's largest deposits; the newest veins were discovered in the southeastern province of Zamora-Chinchipe.
In 1985 Congress passed a new law to encourage foreign exploration and investment in the mining industry. Designed to simplify regulation of the industry, this legislation also offered higher financial incentives for the investor and lower overall taxation and established the Ecuadorian Institute of Minerals (Instituto Ecuatoriano de Minería—Inemin) under the Ministry of Energy and Mines.
Economy of Ecuador
The economy of Ecuador is based mostly on exports of bananas, oil, shrimp, gold, other primary agricultural products and money transfers from nearly a million Ecuadorian emigrants employed abroad. In 2002, oil accounted for about one-third of public sector revenue and 40% of export earnings...

Gold
Gold is a chemical element with the symbol Au and an atomic number of 79. Gold is a dense, soft, shiny, malleable and ductile metal. Pure gold has a bright yellow color and luster traditionally considered attractive, which it maintains without oxidizing in air or water. Chemically, gold is a...

Silver
Silver is a metallic chemical element with the chemical symbol Ag and atomic number 47. A soft, white, lustrous transition metal, it has the highest electrical conductivity of any element and the highest thermal conductivity of any metal...

Copper
Copper is a chemical element with the symbol Cu and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; an exposed surface has a reddish-orange tarnish...
, zinc
Zinc
Zinc , or spelter , is a metallic chemical element; it has the symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table. Zinc is, in some respects, chemically similar to magnesium, because its ion is of similar size and its only common oxidation state is +2...

Uranium
Uranium is a silvery-white metallic chemical element in the actinide series of the periodic table, with atomic number 92. It is assigned the chemical symbol U. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons...
, lead
Lead
Lead is a main-group element in the carbon group with the symbol Pb and atomic number 82. Lead is a soft, malleable poor metal. It is also counted as one of the heavy metals. Metallic lead has a bluish-white color after being freshly cut, but it soon tarnishes to a dull grayish color when exposed...
, sulfur
Sulfur
Sulfur or sulphur is the chemical element with atomic number 16. In the periodic table it is represented by the symbol S. It is an abundant, multivalent non-metal. Under normal conditions, sulfur atoms form cyclic octatomic molecules with chemical formula S8. Elemental sulfur is a bright yellow...

Limestone
Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate . Many limestones are composed from skeletal fragments of marine organisms such as coral or foraminifera....
