I went to the local flea market today and found a rock for sale. I decided to purchase the rock and bring it home to do a little research on it. After surfing the internet I discovered my find to be a mineral rock named‚ “amethyst.” I was interested in finding out where and how this mineral was formed. The more I searched‚ the more I encountered fascinating information. This is a small summary of what I learned. The physical characteristics of amethyst consist of a transparent or translucent

according to the magnetic field strength. Different magnetic separators have different characteristics and performance. The common things have magnetite iron ore (belong to strong magnetic minerals)‚ hematite (belong to weak magnetic minerals)‚ limonite‚ lens iron ore‚ siderite (they are weak magnetic minerals)‚ etc. They are the raw materials of iron and steel industry‚ China’s iron ore grade is low‚ most of the impurities high‚ so more than 80 percent of the need for magnetic separation.

Give two examples of each of the four major mineral groups (silicates‚ carbonates‚ oxides and sulphides). ➔ Silicates: quartz and topaz ➔ Carbonates: magnesite and aragonite ➔ Oxides: uranite and hematite ➔ Sulphides: pyrite and marcasite 4. Distinguish between a rock and a mineral i.e.‚ what are they? How are they similar? How are they different? A rock is a solid mineral formed on the surface of the Earth. A mineral is a natural solid substance (i.e. mountains). They both are solid

I.Introduction Philippines’ minerals are the country’s assets‚ many mining applications and projects in the Philippines are also in small islands with fragile ecosystems that are also highly vulnerable to natural and climate hazards. The Philippines is one of the richest mining deposits globally. According to estimates‚ the Philippines have the fifth largest reserve of minerals in the world. It has the world’s 3rd largest gold‚ 4th largest copper‚ and 5th largest nickel reserves. The Intellasia

The process can recover useful minerals according to the difference of mineral floatability. For example‚ in the mixed flotation of Cu‚ Pb‚ Zn‚ S‚ we can select Pb and restrict Zn first‚ and then activate and select Zn. It is suitable for coarse grain and rich ore.

Albite Albite is a common felspar and is the "pivot" mineral of two different feldspar series. It is most often associated with the plagioclase series where it is an end member of this series. The plagioclase series comprises felspars that range in chemical composition from pure NaAlSi3 O8 to pure CaAl2 Si2 O8 . The various plagioclase feldspars are identified from each other by gradations in index of refraction and density in the absence of chemical analysis and/or optical measurements. Albite
