chromite whereas UG2 concentrates have low sulphide and base metal contents and higher chromite content Smelting of UG2 concentrate requires blending with Merensky or Platreef and as the proportion of UG2 increases higher temperatures and power densities are required to keep the chromite in solution in the slag
Smelting of calcined basic nickel carbonate concentrate in a 200 kW DC arc furnace by M Abdellatif Synopsis Calcined basic nickel carbonate BNC concentrate was smelted in a pilot scale DC arc furnace to produce a nickel metal The furnace was contin uously operated for 12 days 24 hour/day during which twelve different
I have built the Bloomery and have over 500 iron ore Yet when i go to the Bloomery it only shows how to smelt iron into concentrate When i go under smelting it shows an Iron Bar Recipe and states it can be crafted at the Bloomery I am new to the game and now i am lost I can t figure out how to smelt
dead roasted concentrate Fortunately there are alternative feed materials that are sufficiently similar that they can be used for extended large scale demonstration of DC arc smelting in the production of PGMs These materials include medium grade concentrates that are very high in chromite content and low in sulphur as well as tailings
Concentrates are usually specific to particular smelters Thus a lead smelter or a zinc smelter could not smelt a copper concentrate the converse is also true In fact any copper in a lead or zinc concentrate is generally problematic in the smelting/refining processes and would most likely incur a penalty charge see more on penalties below
copper concentrate were consumed As a result around 50 000 tonnes of arsenic were left to be treated As is highly toxic and carcinogenic element and currently still considered as a surplus element in the world meaning that arsenic recovered by smelting is far beyond the application;
In December 2021 Eurasian Resources Group ERG reported that its Kazakhstan headquartered subsidiary Kazchrome had successfully completed trials for the use of floatation technology in the recovery of chromite from tailings at the Donskoy Processing Plant Trials of the novel floatation technology resulted in a chromium oxide recovery of 55% with the specifications of the concentrate
