how do you separate copper minerals from unwanted rock
Copper | Geoscience Australia
These secondary copper minerals may form rich ore in the upper parts of many deposits, and owing to their characteristic green or blue colour, even small amounts are easily seen in the rocks in which they occur. Copper bearing minerals are commonly found in association with minerals which may contain gold, lead, zinc and silver. Resources

Silica | Minerals Education Coalition
Silicon (Si) is a semi-metallic or metalloid, because it has several of the metallic characteristics. Silicon is never found in its natural state, but rather in combination with oxygen as the silicate ion SiO 44- in silica-rich rocks such as obsidian, granite, diorite, and sandstone. Feldspar and quartz are the most significant silicate minerals.
Mineral Mixtures and Mining
Explain that humans mine mineral resources to manufacture items we use every day. The extraction process requires the separation of the unwanted minerals that make up the rock to get to the good stuff we do want! There are several physical and chemical separation techniques that are used to separate materials from Earth.
20.1 Metal Deposits – Physical Geology
Mining and Mineral Processing. Metal deposits are mined in a variety of different ways depending on their depth, shape, size, and grade. Relatively large deposits that are quite close to the surface and somewhat regular in shape are mined using open-pit mine methods (Figure 20.1). Creating a giant hole in the ground is generally cheaper than making an underground mine, but it is also less ...
Copper Mining and Production Processes Explained
Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
What is the difference between a rock and a mineral?
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.

The following is designed to help you identify common rocks and minerals found in the Upstate of SC and surrounding areas. You will find some practical information about identifying minerals and you will be guided through a few simple tests you can do at home that will assist you with narrowing the possible identification of your specimen(s).
Remove unwanted rock by picking, hammering at specimens to be cleaned. Wire brush rock to remove loose, soft material. Soak in muriatic acid (hydrochloric) approximately 1 hour. Sometimes toilet bowl cleaners contain this acid. This soaking removes all the green/brown oxidation from copper, plus any calcite is dissolved.

How to Separate Precious Metal | DoItYourself
· A wide variety of different types of electronics and other objects contain at least one type of precious metal. In many cases, the trace amounts of these metals are fused together inside of the object. In order to recover those metals once the object has worn out or broken, you''ll need to properly know how to separate the metal.

Chapter overview. 2 weeks ''Mixtures'' was first introduced in Gr. 6, so learners should already be familiar with these concepts. Learners would have also looked at some of the physical methods of separating different types of mixtures (including hand sorting, sieving, filtration), and this year we will explore some additional methods in more detail (including distillation and chromatography).
extraction of metals
Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time. Copper can then be extracted from the copper(II) sulphate solution. But, in many cases, it is possible to separate the metal compound from unwanted rocky material by physical means.
Froth Flotation Process
· The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
