Following are the percentage of reinforcement steel generally required per different components. Its values can vary from structure to structure, and can be assumed from past experiences of similar structure. For slabs = 1.0 of concrete volume. For Beam = 2 concrete volume. For column = 2.5 of concrete volume. For RCC Roads, 0.6 concrete.

The average cost of concrete is anywhere from $200 – $300 per m3 (cubic metre), though you could pay as much as $350 for 40 MPa strength. Variations in cost are due to local prices differing slightly, the type of concrete you order, and any additives or admixtures required.

The above pre-treatment stages can be changed based on ore mineralogy. For a complex Au–Ag ore, direct cyanide leaching resulted in only about 47 and 19 extraction of gold and silver even after very fine grinding at 38 m.Diagnostic leaching was carried out to assess the nature of refractoriness [29].Depending on the results of the diagnostic test results, extraction strategies for gold.

Nov 07, 2016 As gold usually appears in very low concentrations in mineral deposits, it is usually measured in grams per tonne, and the average ore grade can vary significantly from one mine to another. Usually open cut mines have lower grades, around 1 to 4 g t, while underground mines can reach up to 8 to 10 g t [ 36 ].
