Carbonate-hosted lead-zinc ore deposits and pyrite thus form. Commonly MVT deposits form by the combination of hydrocarbon pyrolysis liberating zinc-lead ions and sulfur to form an acidic solution which dissolves the host carbonate formation and replaces it with massive sulfide accumulations. This may also take the morphology of fault-hosted stockworks, massive tabular replacements and so forth. Porous limestones may form disseminated ores, however most MVT deposits are massive sulfides with knife-like margins between carbonate and sulfide mineralogies. Ore minerals in carbonate replacement deposits are typically lead sulfide, galena, and zinc sulfide sphalerite. Weathered equivalents form anglesite, cerussite, smithsonite, hydrozincite and secondary galena and sphalerite
Mineral industry of Europe a row; the increase was 2% from the previous year, and production amounted to almost 89.1 million tons. Of all the global market mining of ore, eastern Europe was the smallest region accounting around just 1% of the market, the use of robots in the metal ore mining industry is improving the efficiency and productivity of mines and reduces operational costs. The EU metallic mining sector produces a wide range of ores yielding metal substances. Mineral industry of Europe The European mining industry has a long tradition, right now it is by far the continent's most modern and innovative industrial
