(d) % Weight Recovery is essentially the inverse of the ratio of concentration, and equals 100·C/F = 100·(f – t)/(c – t). (e) Enrichment Ratio is calculated directly from assays as c/f, weights are not involved in the calculation. Example Calculations: Problem: A copper ore …

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.

Sep 23, 2013· Selling Metal Concentrates: Payable Metal, Treatment Charges, Penalties, Terms of Sale In discussions with investors over the past few months, I have observed that most do not understand the relationship between gross metal value in a concentrate and the net percentage of that gross that the seller will actually receive.

When the preliminary feasibility study of a mineral project has not been completed yet, but you do want to estimate the mineral deposit value, you can calculate the potential value of a mining project by the back-of-the-envelope calculation described in this article.

Percent recovery computes the percentage of an original substance that is recovered after a chemical reaction is completed. These mainly include purification reactions. It also determines their efficiency. This ScienceStruck article explains how to calculate the percent recovery of any purified substance.

recovery from this residue achieved 96% silver extraction. These favorable technical outcomes led to an economic assessment for this option. The capital cost of a CESL facility processing 50,000 tpy of high bismuth grade, copper concentrate was estimated to be in excess of $100M with an annual operating cost of $14M/yr. Economics were found to

Jul 31, 2019· It’s very clear that producing a separate copper concentrate with a high silver content is much more valuable than seeing the silver end up in the zinc concentrate. And sure, while Cerro Las Minitas doesn’t contain a lot of copper and the 68% recovery rate isn’t that great, it does have the potential to move the needle.

One way to avoid this is to roast copper concentrate in the presence of lime or limestone, which captures the sulfur as CaS or CaSO 4. The aim is to produce metallic copper as one of the products, while capturing substantially all the sulfur. The copper can then be leached in ammonia for subsequent recovery.

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Dependence of mine revenue on the grade of copper concentrate 549 Parameter A in formula (3) can be determined experimentally by using a series of observations { } and {β} or by using the hypothesis that it will progress as in Fig. 3a. Then, by knowing the current value and β parameter A can be adjusted iteratively for compliance of the calculated result with the measured one.

calculation for recovery on copper concentrate. Calculating Copper Recovery Rate For Scrap Cables - iScrap App Once you have the weight of your copper wire on the inside of the cable, take that number and divide it by the overall weight of the sample and the result will be the percentage of copper recovery rate from your scrap cable or wire.

As a result, the copper and gold net smelter returns for copper concentrate sold to Smelter A are equal to $511 and $515 per tonne of concentrate, or $48.01 and $48.37 per tonne of ore. When these numbers are divided by the mill feed grade, the copper and gold NSR factors are equal to $20.69 per % Cu and $18.97 per gram of gold.

process at a concentrator. In the first flotation stage, as much copper as possible is recovered in a rougher concentrate so that as little as possible goes to the tailings. To increase the copper recovery rate, often these tailings are leached with sulfuric acid. After regrinding, the rough concentrate is -2 of 11-
