    1.1 PHASES OF A MINING PROJECT

    Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The

    Chemical tests for the metal content of various ores

    Silver: silver ores may be detected by dissolving a small quantity in a test tube with a few drops of nitric acid. Boil until all the red fumes disappear. Let the solution cool, and add a little water. Filter the whole, and add a few drops of muriatic acid, which will precipitate the white chloride of silver.

    Mica. Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.

    Carbon Reduction Method Chemistry Tutorial

    The more active (or reactive) a metal is, the more stable the compound it forms and the greater the energy required to produce the metal from its ore. Very active metals ( Group 1 , Group 2 and aluminium) require electrolysis to extract the metal while very inactive metals like gold and silver can occur in nature as the element so require no ...

    How is Silver Mined | APMEX®

    Silver also occurs alongside lead, copper and zinc ores, which is why nearly 50% of mined Silver today is obtained when processing other kinds of ore. Silver is separated from this ore using a chemical process known as smelting. To begin a new Silver mine, a system of multi-layered crosscuts are made.

    Metals are taken from the rocks of an ore deposit using chemistry. In processing ore to recover the metal of interest, steps of the process can be divided into (a) the steps to prepare the metal for separation from the rest of the rock or other metals, and (b) steps to actually remove the metal from the rock and unusable or uninteresting parts ...

    Silver, Chemical Element

    Chemical properties Silver is a very inactive metal. It does not react with oxygen in the air under normal circumstances. It does react slowly with sulfur compounds in the air, however. The product of this reaction is silver sulfide (Ag 2 S), a black compound. The tarnish that develops over time on silverware and other silver-plated objects is silver sulfide.

  • Heap Leaching of Gold and Silver Ores

    Heap Leaching of Gold and Silver Ores

    Jan 01, 2016 Silver is usually not as reactive as gold with cyanide. This is because gold almost always occurs as the metal, whereas silver may be present in the ore in many different chemical forms, some of which are not cyanide soluble. Gold recovery efficiency from operating heap leaches is typically ∼70%, although it can range from 50% to 90%.
