This is the Copper Ore to Copper Ingo smelting section of the Jumpstart base by Nilaus.
It will need one full yellow belt of Copper Ore (six per second, or two miners covering 6 veins each). The Copper Ingots at the end of the line are simply stored and not used to create anything in the mall.
This Blueprint is under 150 facilities, which requires the technology research Mass Construction Lv2.
