How Mining and Casinos Are Intertwined

Iron ores are minerals found in the ground, containing iron in sufficient quantities for their extraction and industrial development. The metal produced from these ores is the metallurgical basis of modern civilization. It is used everywhere in any direction of human activity: from space exploration to the manufacture of ordinary everyday items.


Iron ores are classified according to a number of criteria

First of all, the most important factor economically is the percentage of iron. Therefore, the ores are divided into a number of types:

  • Rich – the content of a useful mineral exceeds 50%.
  • Ordinary ores contain 25 – 50% iron.

Raw materials that are not rich in iron do not have a significant amount of iron. It is not more than 25% in them. That is why such ores are called poor.

As for the chemical composition, these are mainly various compounds of iron with oxygen, water and carbon, found in nature in the form of:

  • brown iron ore – limonite,
  • magnetic iron ore – magnetite,
  • red iron ore – hematite,
  • spar iron ore – siderite.

Iron-bearing deposits usually have the following types of ores:

  • Apatite-magnetite, contained in carbonatites.
  • Goethite-hydrogoethite, located in weathering crusts.
  • Magnetite and magma-magnetite in the environment of skarns.
  • Magnetite-hematite, found among iron quartzites.
  • Martite and martite-hydrohematite – especially rich in mineral ores in iron quartzites.
  • Titanium-magnetite, as well as ilmenite-titanomagnetite, located in mafic and ultra-basic rocks.

To complete the picture, it should also be noted that deposits of this type of minerals are formed as a result of:

  • high-temperature exposure – magmatogenic deposits;
  • weathering of mountain rocks and sedimentary deposits – exogenous;
  • sedimentary activity, subsequently subjected to a significant impact of pressure and temperature.

Factors that determine the value of ores The profitability of the development of each particular deposit is explained by a whole set of conditions:

Quantitative and qualitative composition of the main mineral, that is, again, the concentration of iron in the ore. It is clear that the higher it is, the better. This factor has a decisive influence on the yield of the final product and the smelting process itself. It is he who increases the productivity of the equipment and does not require additional costs for enrichment.

As for the reserves of the deposit, the necessary minimum for the return on investment, according to economists, is 600 million tons. Smaller sizes do not cover the costs of creating the necessary infrastructure: production facilities, engineering networks, roads, housing, public facilities.

Also, the rest of the composition of the ore is of great importance – that is, waste rock, which, depending on its qualities, can increase or decrease the yield of slag.

The presence of impurities plays a very important role. If useful ones improve the quality of the smelted metal, then harmful components must be disposed of by complex technological methods or their adverse effects must be neutralized.

The physical and metallurgical properties of the ore must also be taken into account. Washability, strength, softenability, lump size, moisture content are all factors that determine the potential value of iron ore deposits.

In addition, the ability of the source material to recover – to give off oxygen, which significantly speeds up the smelting process, is also important.

One of the conditions that determine the economic feasibility of development is the depth of the ore body and its location, depending on the distance from developed economic regions. Overcoming these problems requires laying roads, providing the field with human and energy resources.

It’s no secret that I do a lot of iron. Especially casino inventory. People manufacture and supply a full range of standard and custom-made gaming equipment for land-based casinos, including roulette wheels, roulette winning number displays, poker tables, gaming tables, casino and slot machine chairs, gaming table covers, playing cards, playing chips and other casino accessories.

The roulette table is the king of the casino. And it’s made of iron. The roulette table can only be used as a roulette table. The complex device is designed for the sole purpose of launching a fast-paced gambling game.

The very concept of “roulette”—roulette is based on the word roue – wheel. The whole massive structure is based around a rotating wheel – a high-precision mechanism, produced with the latest technology and the best, optimally selected materials.

  • The precision of the fit of the parts is no less than the precision of the assembly of the spaceship.
  • Longitudinal and lateral runout of the wheel is eliminated thanks to the double support system.
  • The standard block of the mechanism does not require special care and is easily replaced.
  • Physical deformations that could affect the trajectory of the ball are excluded.

What the roulette

table is made of The roulette table consists of the plane of the playing field with markings for bets and the drum of the rotating disk itself.

In the European (French) version, the wheel is located in the center, the playing fields are spaced apart at the edges.

The table for American roulette is asymmetric – the playing field is the only one located at the end of a long tabletop, the roulette wheel is shifted to the edge.

There are also two-tier models.

Any variety of roulette tables differ in solid dimensions. Height corresponds to the growth of a standing dealer. For 15-20 minutes, the croupier does not have time to get tired, and comfortable chairs are provided for guests.

Six players are seated in a sector with a lined betting table. Every experienced player has his favorite place, where it is easier for him to place bets and more convenient to look at the table.

So whatever one may say, iron is used everywhere.
