blister copper การใช้

• Initially the black copper was converted to blister copper in the ISASMELT furnace.
• In 1903 it was upgraded to produce blister copper.
• The blister copper goes to six anode furnaces which feed three anode casting wheels.
• This raised the production of blister copper to 155, 000 t / y.
• The slag is then tapped and the remaining copper matte is then converted to blister copper.
• Ore mined at the Kalkadoon was smelted at Mount Cuthbert from 1917 and sent to Britain as prime blister copper.
• The contract also granted the Phelps Dodge Corporation to deliver a minimum of one million pounds of blister copper for over three years.
• Nevertheless, 5447 tons of blister copper was produced in 1911, rising to 6690 tons in 1912-the company's best year.
• Although 3200 tons of blister copper was produced in 1913, production fell to 1840 tons in 1914 and the workforce dwindled to only 40 men.
• In most cases, the slag can be discarded, perhaps after some cleaning, and the matte is further treated in converters to produce blister copper.
• From its inception, the copper smelter had been producing blister copper, originally for sale and then for refining at MIM's copper refinery in Townsville.
• This economically symbiotic relationship lasted until 1922, when Phelps Dodge provided 90 percent of the blister copper Nichols Copper Company used to produce 100 percent pure copper.
• This economically symbiotic relationship lasted until 1922, in which Phelps Dodge provided 90 % of the blister copper Nichols Copper Company used to produce 100 % pure copper.
• The second stage of converting is aimed at oxidizing the copper sulfide phase ( purified in the first stage ), and produces " blister copper ".
• The customer in this case can be a smelter, who on-sells blister copper ingots to a refiner, or a smelter-refiner which is vertically integrated.
• There were 7 relatively small reverberatory furnaces in the smelter and, in the 1930s, a pair of were added to produce blister copper ( 98 % copper ).
• First, in the 1987-91 period, there was a substantial increase in the output of refined copper, as well as a relative decline in the production of blister copper.
• The new smelter was blown in September 1910, a month after the first train arrived, and it ran well, producing 2040 tons of blister copper by the end of the year.
• The new furnace commenced on 16 January 1918 and 77, 482 tons of ore were smelted yielding 3580 tons of blister copper which were sent to the Bowen refinery before export to Britain.
• The purity of this product is 98 %, it is known as " blister " because of the broken surface created by the escape of sulfur dioxide gas as blister copper " pigs " or ingots are cooled.
