La produzione mondiale annuale di rame si aggira attorno ai sedici milioni di tonnellate.
I minerali rameici hanno contenuti medi che variano tra lo 0.6% ed il 2%. I processi che portano dall’estrazione alla disponibilità di rame puro lingottato sono molto dispendiosi in termini energetici, tanto da giustificarne il riciclo, che nei paesi industrializzati fornisce circa il 40% dei consumi.
Alla luce di questi dati, la recente scoperta fatta dal Saudi Geological Survey sembrerebbe essere molto interessane, ma dovrebbe ancora essere valutata appieno nel suo rapporto prestazioni/costi. Dati questi che potrebbero essere disponibili già a fine 2017.
A quanto è riferito il bacino rameico potrebbe essere:
«of one of the biggest copper stocks in the world».
In ogni caso, se i futuri riscontri fossero coerenti con questi dati preliminari, l’Arabia Saudita potrebbe fare evolvere la propria economica in modo strategicamene sostanziale, non essendo più questa legata unicamente all’estrazione del greggio.
→ Saudi Gazette. 2016-11-09. Hundreds of tons of copper discovered in the Kingdom
The Saudi Geological Survey (SGS) has discovered hundreds of tons of copper in a 3,000 sq. meter surface, while mining processes shows many indications to the discovery of new gold mines that will significantly contribute in raising the total production of the Kingdom to more than 10 ton annually.
These discoveries will support the Saudi Vision 2030 in relying on non-oil revenues and will remarkably contribute in maximizing the production of copper in sync with the new strategy to establish a copper smelter to provide all the copper-based industries with their main primary material.
Zohair A. Nawab, SGS president told Asharq Al-Awsat that the authority has carried on surveys and processes of mineral mining in a surface of two million sq. km and succeeded with its experts in discovering many important sites, which are expected to remarkably contribute in growing the Saudi economy.
Zuhair added that the government has worked on a strategy to promote mining investment by opening discovery perspectives for foreign investors; the plan to attract specialized international company in this field was set and many mining and excavation authorizations will be issued for these companies in correspondence with the Vision 2030.
Nawab said that the recent search processes led to the discovery of one of the biggest copper stocks in the world; experts are currently working on determining quantities in specified zones, which will be opened for foreign investments in this field and which secures important revenues to the national economy.
The SGS president added that most of the Saudi Arabian production of copper does not provide primary materials, except for the mine located in the south of the Kingdom.
Nawab continued saying that the mining sector represents an important pillar in the national development because it opens different work fields.
The copper sector requires many investments to produce copper wires and mines that intervene in industries that are expected to increase the national supply and raise the value of the national economy.
Finally, Nawab assured that the Kingdom intends to expand the industrial sector and the excavation of mineral products including rare types as part of the government’s strategy for the coming phase based on the results of latest discoveries.
