In which of the following order is copper produced?

The correct order in which copper is produced is: blasting - crushing - grinding - floating - smelting. The process starts with blasting, which involves drilling and explosives to break up the rock. The resulting pieces are then crushed into smaller pieces using crushers. After crushing, the ore is ground into a fine powder in a grinding mill. The next step is called flotation, where chemicals are added to the ground ore to make the copper particles attach to bubbles, which are then separated from the non-copper particles. Finally, the copper concentrate is sent to a smelter where it is heated at high temperatures to melt and separate the copper from other minerals in the ore. Therefore, the correct answer is: blasting-crushing-grinding-floating-smelting.
