Chuquicamata, in Chile, ... The human body contains copper at a level of about 1.4 to 2.1 mg per kg of body mass. [202] Absorption. Copper is absorbed in the gut, ...
Chuquicamata (/ tʃ uː k iː k ə ˈ m ɑː t ə / choo-kee-kə-MAH-tə; referred to as Chuqui for short) is the largest open pit copper mine in terms of excavated volume in the world. [citation needed] It is located in the north of Chile, just outside Calama, at 2,850 m (9,350 ft) above sea level.
Copper deficiency, or hypocupremia, is defined as insufficient copper to meet the body's needs, or as a serum copper level below the normal range. [1] Symptoms may include fatigue , decreased red blood cells , early greying of the hair, and neurological problems presenting as numbness , tingling, muscle weakness, and ataxia . [ 2 ]
Furthermore, long-term copper treatment (oral intake of 8 mg copper (Cu-(II)-orotate-dihydrate)) was excluded as a risk factor for Alzheimer's disease in a noted clinical trial on humans [94] and a potentially beneficial role of copper in Alzheimer's disease has been demonstrated on cerebral spinal fluid levels of Aβ42, a toxic peptide and ...
Chuquicamata copper mine in 1984. Chile has the world's largest copper reserves, and is the largest producer and exporter of the metal. [3] Notable copper mines include Chuquicamata and Escondida. Chile accounts for five percent of the Western Hemisphere's gold production, of which 41 percent is a by-product of copper extraction. [3]

The suggested safe level of copper in drinking water for humans varies depending on the source, but tends to be pegged at 1.3 mg/L. [2] So low is the toxicity of copper that copper(II) sulfate is a routine reagent in undergraduate chemistry laboratories.
The ATP7B protein is located in the trans-Golgi network of the liver and brain and balances the copper level in the body by excreting excess copper into bile and plasma. Genetic disorder of the ATP7B gene may cause Wilson's disease, a disease in which copper accumulates in tissues, leading to neurological or psychiatric issues and liver diseases.
