ducing copper: the direct and indirect costs incurred in mining, concentrating, smelting, and refining copper. They include transportation to the mill, smelter, and refinery, and metallurgical processing of the byproducts. Some estimates of operating costs also include the freight charges for transporting the refined copper to market.4
The three product solution illustrated above can be somewhat simplified by taking an intermediate tailings sample between the two stages of concentration i.e., a copper tail (zinc feed) sample in the previous example. Then, adding the notations: Copper tail (zinc feed) = CT with copper and zinc assays = c 5 and z5. Assume mill feed, F, as Unity 1
The net smelter return (NSR) refers to the revenues expected from the mill feed, taking into consideration mill recoveries, transport costs of the concentrate to the smelter, treatment and refining charges, and other deductions at the smelter.

After our product has been weighed we will need to calculate the percent recovery. The equation for percent recovery can be seen in equation 7. (7) Percent Recovery = (mass of Cu recovered / mass of initial Cu) . Procedure . 1. Weigh 0.350.40 g of copper wire and place into a
Percent recovery = amount of substance you actually collected / amount of substance you were supposed to collect, as a percent. So another way of putting it: Percent Recovery = (pure/impure) x 100. Let''s say you had 10.0g of impure material and after recrystallization you collected 7.0 g of dry pure material. Then your percent recovery is 70%
Oct 10, 2007 · Best Answer: I assume you are doing the copper cycle lab. There are multiple reasons why the percent recovery is over . a) The copper was not completely dry b) The "copper" you recovered wasnt pure and contained one of the intermediate copper complexes (nitrate,hydroxide,etc.) c) There is some other

The metal recovery rate, or also known as the mineral recovery percentage, indies what percentage of valuable metals are expected to be available for sale after the refining process has taken place.The metal recovery rate can be found in a mining company''s National Instrument 43101 or in a similar applicable international reporting standard.
Property Tax and Millage Calculator. What''s a mill? Do you remember when you were in school and you were working on decimals? The first number after the decimal point is tenths (.1), the second number after the decimal point is hundredths (.01), and going out three places is thouhs (.001), or "mills".
Chemical Reactions of Copper and Percent Yield KEY Prelab (Review Questions) 1. Give an example, other than the ones listed in this experiment, of redox and metathesis reactions.
What Is the Formula Used to Find Percent Recovery? When purifying a substance in chemistry, use (collected mass/starting mass)*100 to calculate percent recovery. This formula is also commonly stated as (pure product recovered/crude material used)*100.
Calculator for Rolled Length of Roll of Material Calculates the rolled length of a roll of material when the outside diameter of the material, thickness of the material, and the diameter of the hole in the center or the tube on which the material is wound are given.
The value of the free copper, gold and silver in a copper concentrates for a copper smelter is depending on the recovery rate, LME copper price and LMBA gold and silver price. In this example the recovery rate for a copper smelter is 98.0%. The value of free gold and silver is normally greater than the value of the free metal for copper.
Percent recovery computes the percentage of an original substance that is recovered after a chemical reaction is completed. These mainly include purifiion reactions. It also determines their efficiency. This ScienceStruck article explains how to calculate the percent recovery of any purified substance.
CuEq Metal Equivalent Calculator for Mining Results. Use this simple metal equivalents calculator to calculate common (and uncommon) equivalences. For each metal select the grade and the market price to be used in the calculations. You may also select a recovery %, the amount of assayed material that can actually be recovered during
