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 ]
Chuquicamata, in Chile, is one of ... copper salts are used to test for reducing sugars. ... The human body contains copper at a level of about 1.4 to 2.1 mg per kg ...
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 ...
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.
Trace metals within the human body include iron, lithium, zinc, copper, chromium, nickel, cobalt, vanadium, molybdenum, manganese and others. [ 1 ] [ 2 ] [ 3 ] Some of the trace metals are needed by living organisms to function properly and are depleted through the expenditure of energy by various metabolic processes of living organisms.

Chuquicamata é a maior mina a céu aberto de cobre do mundo por volume escavado e sua exploração foi iniciada em 1882 com a extração de ouro e cobre. Tem 4,5 km de comprimento, 3,5 km de largura e 850 metros de profundidade, o que faz dela a segunda mina a céu aberto mais profunda do mundo (depois da mina de cobre Kennecott em Utah ...
