Sheet metal products: how to calculate production cost
The formula to calculate the cost of the machining is the following: For example, with a cycle time of 12 seconds, efficiency 80,5% and a Machine hourly cost of 77,3 Euro we obtain: MACHINING COST = 77,3 * 12 / 0,805 / 3600 = 0,32 Euro. So the total direct cost of the production for one piece is:

How to Calculate Grade and Recovery with Examples
For example, a copper ore grade of 1% means that in 100 tons of the ore, we have 1 ton of copper. If the copper ore contains 40 tons of calcite gangue, we can also say 40% of calcite in the ore. A gold deposit with a grade equal to 5 g/t (gram per ton) means that in one ton of the ore, we have 5 grams of gold.

Copper Concentrates
The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

Copper Calculation
Copper Weight. The copper weight is calculated by the cross section of a cable x 9.6 and will be shown in kg / km. For example FLRY 1.50 mm² has a copper weight of 14.4 kg / km (9.6 x 1.5). DEL. DEL is derivated from the German exchange "Deutsche Elektrolytkupfernotiz für Leitzwecke" and is the listing for 99.5 % pure copper.

copper extraction and purification
Extracting copper from other ores. Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.
