mining stone in geology are referred to as crustal earth, which contains valuable metals and elements. Extraction costs include: concentration of mineral or metal ore, as well as how it occurs on the cost of stone extraction The mine affects.The floor stone is one of the main interior decoration of the building, and often the first option for use on the floor of the rooms and halls is natural stones that give warmth and sense of nature to the home environment.Stone slabs, travertine, marble and granite are popular floor stone.Mineral stones are used in different parts of the building due to its advantages.For example, the material and internal structure of the stone used in the stairs are very different from the stone used in the building or floor of the building.There are a lot of mines in the world due to the geographic conditions. But all countries are not able to process them and they have to export mines in the first form.Other uses of stones include the use of energy and mental effects of the rocks to create a sense of relaxation and increase concentration.Salt in the rocks causes them to corrode. Among other things that damage the rocks, there is pollution, freezing and temperature changes, rot in metal parts in the rock, and poor operation.Natural stones include the following groups: Basalt group, Flint group, Gabbro group, Granite group, Sand and igneous rock group, Hornfel group, Limestone group, Schist group, Profi group, Quartzite group.
biggest stone mine in the world

The company produces, in addition to iron ore, nickel, copper and mimeim, Valletta Corporation.Rutinto is the second largest producer of iron ore and four groups of aluminum, copper, diamonds, energy and minerals are among other products of this producer.The third is the BH-Billion, a British-Australian company, located in Melbourne, Australia.Fortressy Metals Group is one of the least costly producers of iron ore in the world.
most cost effective mining stone methods
The valuation of mining stones takes place in different ways. Some of the stones are therapeutic, while others are used in decorations other than decorations such as decorations of utensils, clothing and jewelry. The origin and percentage of mineral or Metal is another part of the valuation of rocks. Also, some of the rare stones, such as germ-jute, are very valuable.Some stones have certain characteristics such as heat resistance, acid resistance and alkali resistance.Minerals forming minerals are characterized as solid, inorganic, homogeneous, natural, inorganic and chemical, and there are 24 types of mineral rock in nature.

Brazil, India, Australia and South Africa are among the largest producers of mining rocks, and due to having a lot of resources in this field, they have commercial exchanges at more reasonable prices. But rocks such as turquoise are very rare and exclusive It should be noted that such rocks should be made from countries like Iran, but at a higher cost.Fortesky Metal Group in Australia is also one of the cheapest manufacturers in the field.
mining stone costs an effects on the price
Mining minerals extracted from minerals have a very diverse appearance and internal structure and consist of various minerals such as magnetite and hematite. After extraction of iron ore to improve the grade, the impurities removed are processed.The pricing of products derived from mines is interconnected. For example, in some cases, the pricing mechanism for iron ore is that the concentrate rate is a multiple of the steel price, and basically the stones Mines are priced on the stock market.
Pricing of mines on the stock has some advantages:
- Create fair and equitable market prices
- Cash payment on time
- Find foreign customers and obtain export licenses
- Private sector investment
