copper-bulk reduce

Question 1

4 step process

Answer 1

1-mining
2-concentration
3- smelting
4-refining

Question 2

what happens in mining

Answer 2

mine the copper ore- the heavy, bulky ore is mostly waste AKA “ganue”

Question 3

what is ganue

Answer 3

excess ore from mining that is waste

Question 4

what happens in concentration

Answer 4

concentration mills crush and grind ore into fine particles, mix them with wate, chemicals, and filter and dry-copper concentrate is about 25% copper

Question 5

why are concentration mills of copper near copper mines

Answer 5

they transform heavy, bulky copper into lighte, much higher value per weight

Question 6

what happens in smelting

Answer 6

remove impurities

reducing

Question 7

what happens in refining

Answer 7

purified copper is treated at refineries to make it 99.99 pure copper-after this, little weight loss occurs so proximity to mines, concentration mills, and smelters is less critical

Question 8

where is copper in USA

Answer 8

2/3 in Arizona (SW USA)- so the state aalso has alot of smelters and mills
