The Ore is actually not a simple hard rock. An ore is a type of rock that contains sufficient minerals with important elements including metals that can be economically extracted from the rock. The ores are extracted through mining; these are then refined often via smelting to extract the valuable elements. It is in the consistency of course sand. Usually, The material is removed from the mine and run through a sand screw system to separate the fine precious metal bearing material from the gravel and stones. Depending upon the system of recovery it may need to grind to a finer aggregate but that is not likely. Ore Basically define by its primary element such as when there is higher content of Platinum it is basically identifies as Platinum Ore, Same as for rich Gold deposits call Gold Ore.
Currently we are working with following Ores:
- Gold Ore
- Platinum Ore
- Iron Ore
- Copper Ore
- Bauxite
Trade
We do trade worldwide various types of Ore. Primarily Gold Ore, Platinum Ore, Iron Ore, etc.
Ores are traded internationally and comprise a sizeable portion of international trade in raw materials both in value and volume. This is because the worldwide distribution of ores is unequal and dislocated from locations of peak demand and from smelting infrastructure.
Most base metals (copper, lead, zinc, nickel) are traded internationally on the London Metal Exchange, with smaller stockpiles and metals exchanges monitored by the COMEX and NYMEX exchanges in the United States and the Shanghai Futures Exchange in China.
Iron ore is traded between customer and producer, though various benchmark prices are set quarterly between the major mining conglomerates and the major consumers, and this sets the stage for smaller participants.
Other, lesser, commodities do not have international clearing houses and benchmark prices, with most prices negotiated between suppliers and customers one-on-one. This generally makes determining the price of ores of this nature opaque and difficult. Such metals include lithium, niobium-tantalum, bismuth, antimony and rare earths. Most of these commodities are also dominated by one or two major suppliers with >60% of the world's reserves.
Difference between Ore and Mineral:
[su_table]
| Ores | Minerals/Metal |
| Ores are concentrations of minerals in rock that are high enough to be economically extracted for use. | Minerals are naturally occurring inorganic solids with a crystalline structure and a definite range of chemical formula. |
| A mineral or an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined or extracted is an ore. | A mineral occurring in sufficient quantity and containing enough metal to permit its recovery and extraction at a profit. |
| Ore mined for its Mineral/Metal content is an ore. | Minerals/Metals are contained in ores |
| All ores are minerals | All minerals are not necessarily ores. |

What is an ore?
Ore is defined as an economic concentration of minerals. The richness of ores can be vastly different, depending on the minerals and elements involved. Chromium ore consists mainly of the mineral chromite, of which chromium is a major constituent. Most vanadium ores are made of magnetite, but vanadium is only a minor element of that mineral. Platinum ore contains only traces of platinum-rich minerals, Gold ore contains only traces of Gold-rich minerals, and most of them are so tiny that they cannot be seen by the naked eye. The chromium ore contains 25 percent chromium, the vanadium ore 2 percent vanadium, and the platinum ore 0.0008 percent platinum and related elements.
Ore Deposits
Mineral resource classification An ore deposit is an accumulation of ore. Now this is distinct from a mineral resource as defined by the mineral resource classification criteria. An ore deposit is one occurrence of a particular ore type. Most ore deposits are named according to either their location, For example, the Witswatersrand, South Africa, or after a discoverer example the Kambalda nickel shoots are named after drillers, or after some whimsy, a historical figure, a prominent person, something from mythology or the code name of the resource company which found it, Example MKD-5 is the in-house name for the Mount Keith nickel.

Extraction
Mining The basic extraction of ore deposits follows these steps:
- Prospecting or exploration to find and then define the extent and value of ore where it is located ("ore body").
- Onduct resource estimation to mathematically estimate the size and grade of the deposit.
- Conduct a pre-feasibility study to determine the theoretical economics of the ore deposit. This identifies, early on, whether further investment in estimation and engineering studies is warranted and identifies key risks and areas for further work.
- Conduct a feasibility study to evaluate the financial viability, technical and financial risks and robustness of the project and make a decision as whether to develop or walk away from a proposed mine project. This includes mine planning to evaluate the economically recoverable portion of the deposit, the metallurgy and ore recoverability, marketability and payability of the ore concentrates, engineering, milling and infrastructure costs, finance and equity requirements and a cradle to grave analysis of the possible mine, from the initial excavation all the way through to reclamation.
- Development to create access to an ore body and building of mine plant and equipment.
- The operation of the mine in an active sense.
- Reclamation to make land where a mine had been suitable for future use.
