CARBONATE ORES EXPERIMENT
Thermal decomposition of metal carbonates- Learn Chemistry
f Repeat the experiment with the other metal carbonates supplied, the carbonates of some of the less reactive metals are decomposed has been used in the extraction of these metals from ores that contain the metal as a carbonate, for example zinc carbonate (calamine). Carbonate.
Extracting metals from rocks- Learn Chemistry
Class practical. Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO 3(OH) 2 experiment involves producing copper from copper(II) carbonate. The copper carbonate is first heated to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.
Carbonate - Wikipedia
In chemistry, a carbonate is a salt of carbonic acid (H 2 CO 3), characterized by the presence of the carbonate ion, a polyatomic ion with the formula of CO 2− 3 . The name may also refer to a carbonate ester , an organic compound containing the carbonate group C(=O)(O–) 2 .CAS Number: 3812-32-6Chemical formula: CO2−, ₃Conjugate acid: BicarbonateMolar mass: 60 g·mol−1
United Nuclear - Uranium Extraction Experiment
However, Carnotite and its associated matrix minerals are far too alkaline for Acid extraction and many of the minor Uranium ores will not dissolve in acid. Alkaline extraction is called for when dealing with Carnotite ore. To begin, you'll need 200 grams of powdered Uranium ore, 50 grams of Sodium Carbonate,[PDF]

In today’s experiment, we will produce copper metal from a copper-containing mineral, using the steps that early humans might have first used in producing copper metal from ore. The starting material is the green mineral malachite, which is a basic copper carbonate, Cu 2 CO 3 (OH) 2
Calcium carbonate - Wikipedia
Calcium carbonate is a chemical compound with the formula Ca CO 3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs.Chemical formula: CaCO₃Molar mass: 100 g/molMelting point: 1,339 °C (2,442 °F; 1,612 K) (calcite), 825 °C (1,517 °F; 1,098 K) (aragonite)Solubility in water: 0 g/L (25 °C)

how to measure carbonate in an ore sample
Apr 18, 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.
