1. Iron ore - supply and demand outline 1.1 Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade.
Get PriceIn 2019, Kiruna produced 14.7Mt of iron ore products. The production in 2018 and 2017 was 15Mt and 14.8Mt, respectively. The mine produced 50,000t of ore feed material a day in June 2020. Mining at the site was briefly halted in 2019 after an earthquake of magnitude 4.1, the country's biggest-ever, occurred in
Get Price09.04.2015· Iron ores can be grouped into types of similar geological occurrence, composition and structure. The following is a simplified classification which is based on genesis of the deposits and geological environment. It shows the main modes of occurrence of iron ores as well as it illustrates the varied geology of iron ore deposits.
Get PriceGold Leaching ( carbon in leach) was developed from CIP ( Carbon In Pulp), is characterized by less process flow, timesaver in the leaching process, thus reducing the production expenditure. Besides, advanced extraction technology improving the efficiency of gold extraction. The CIL production line is wider use than CIP in the mineral industry.
Get Pricemetal ores (<1% copper, <1g/ton gold, < 0.5% nickel) previously considered uneconomical, became feasible with introduction of heap leaching technologies (Marsden, 2009). In consideration of ore types, a generalized diagram showing the applicable ore beneficiation technologies for oxide and sulphide ores versus ore grade is given in Figure 2.
Get PriceThe principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (<10 µm) locked
