Thermal decomposition of metal carbonates
The aim of this experiment is to compare the reactivity of some different metal carbonates. This experiment can be carried out as a class exercise, individually or in pairs. Because of the toxicity of lead compounds, it may be best to leave lead carbonate out with less reliable classes. The experiment should take about 40–45 minutes. Equipment

Bronze is not an element (like gold and silver) but an alloy ( metal mixture) of copper and tin . Ores of. both copper and tin are easily reduced by heating with carbon. This would have occurred accidentally as people lit wood fires. in places where mixtures of tin ore and copper ore existed. The hot burnt wood ( carbon) would have reduced the ...
extracting metals from ores methods
Extraction of Metals from Ores – Different Processes Involved. The basic extraction of metals from ores has the following steps. 1. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later.

What are the 3 environmental impacts of mineral extraction?
What are the environmental impacts of mining iron ore? The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide from diesel generators, trucks and other equipment. The mining of iron ore also causes water pollution of heavy metals and acid that drains from the mines.

Boardworks GCSE Science: Chemistry Extracting Metals
Recycling costs less than extracting metals and can be profitable. One problem is that metallic materials in recycled objects are often mixtures of different metals. This can mean that obtaining pure metals from recycling is more expensive, as it may use more electricity than extracting metals from ores.
