First of all work out how much copper carbonate there is in the ore. That’s not hard. Write this figure down with an appropriate caption. Now check your periodic table for the atomic masses of copper, carbon and oxygen. Work out the molecular mass of a combination of one, one and three of these respectively. Write this figure down. Suppose it’s 78 (it almost certainly isn’t).

18/04/2013 ok, so the investigation that we are doing it on is about finding how much carbonate is in a sample of ores. our hypothesis is: the amount of carbonate in an ore sample can be measured by adding hydrochloric acid to the sample until it stops fizzing. for my planning sheet i have wrote my method for the actual experiment. I have wrote what equipment I need and i have wrote one risk assessment

#### Need help with my science ISA? Yahoo Answers

18/09/2013 Goggles and gloves is you are breaking up the ore to get the samples. If you want samples to test try asking in a garden centre or builders merchants for the small shards chipped off stone products. (hopefully some will be limestone) Context why are you measuring carbonate. In itself it will not tell you anything about the metal that is associated with it. After dissolving the rock think about measuring the metal ions in solution such as calcium, iron and copper

#### Decompose Copper Carbonate by Heating and Heasure the

2. Measure out 0.25g of copper carbonate to the nearest 0.01g, remembering to turn the scales after placing the container in which to hold the copper carbonate. 3. Put the copper carbonate into a conical flask and attach a bung, which has a tube protruding from it, so that the rubber tube can be attached easily. 4. Attach the tube connected to the bung by a rubber tube, which is connected to the end of the

#### Extracting copper from copper(II) carbonate Experiment

Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO3.Cu(OH)2. In this experiment, students learn how to produce copper from copper(II) carbonate by heating it to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent. If possible, show the class a genuine sample of malachite ore and artefacts, such as paperweights or polished

#### Chemical tests for the metal content of various ores

The amount of copper in the sample multiplied by 32,000 will be the copper in a ton of the ore. Should copper be suspected, roast the powdered ore and mix with an equal quantity of salt and candle grease or other fat; then cast into the fire, and the characteristic flame of copper first blue and then green will appear. This test is better made at night.

#### Assaying Copper Determination Method

If at a ticketing in Cornwall 985 tons of ore containing 63.3 tons of fine copper (by dry assay) brought £2591 12s., the standard would be £83 15s. This is calculated as follows:— The returning charge is fixed at 55s. per ton of ore. This on 985 tons will amount to £2708 15s. Add this to the actual price paid, and there is got £5300 as

#### Assaying Ores to determine gold content Nevada Outback

The old time prospectors when they were out searching in the field for new veins would do a rough assay by crushing or samples and carefully panning the results. With some experience and a careful examination of the amount of gold present, they could make some excellent visual of the estimates of the amount of free gold in the ore. This method has its limitations, because it is possible to
