Due to increasing chrome content in the feed and the challenges associated with operating high chrome feed, alternative routes to smelting of PGM are ...
Jan 20, 2020 Samancor explores restructuring, job cuts amid drastic chrome price decline. Samancor Chrome has provisionally decided to restructure its mining and smelting operations in a move that will reduce staff and production levels due to the deteriorating chrome markets and rising power costs, Fastmarkets has learned.
3,300-3,800 kWh per ton of metal produced. The cost of electricity counts for about 35-40% of total production cost. Due to the shortage of power supply in South Africa, the cost of electricity has more than doubled since 2008, and a plan has been tabled to increase the electricity price by 16% every year from 2013 to 2018.
stockpiles grew because of the lack of smelting capacity, high production costs and power shortages. The government has also increased its royalty from 2 percent to 5 percent on chrome but subsidizes electricity tariffs for chrome processing 9. As a result, Zimbabwes chrome exports have increased.
raw chrome ore on the international markets, particularly on the Chinese market, the country has generally adopted the policy not to export raw chrome ores. . 2 Figure 1. Zimbabwe Chrome ore production Podiform chromite ore reserves are expected to run out by 2015, and the smelting technology will have
The increasing costs of electric energy and thus the need to reduce the energy required to produce ferrochrome from chromite ore have spurred the innovations in the technologies used for smelting chromite ore. These technologies (Conventional smelting process, Outokumpu process, DC arc route, and Premus process) have been reviewed in this work.
Figure 3.2 Charge mix for production of ferro-chrome Charge mix was fed in the furnace in a 2 to 3 kg batch to ensure the proper smelting and reduction of the pellets. After complete smelting of the charge, furnace was arced for 30 minute more to provide the super heat to the furnace.
The operating costs for the process are significantly lower than those involving smelting as the primary method of upgrading. A centurys supply of premium-priced ferrochrome that could be made in Canada using natural gas, requiring less energy and lowering emissions.
of lumpy ore and briquettes the unit cost per ton of FeCr went down 35% (figure 6). The division of costs by process units is described in item 3.1. Figure 6.
