Pilot-scale sintering tests were carried out using a sinter pot of 320mm diameter under the following conditions: igni-tion time 90s, ignition suction 8kPa, sintering suction 12kPa. Detailed technique has been given in a previous publication.5) 3. Properties and Sintering Behaviour of Chinese Magnetite Concentrates 3.1. Magnetite Concentrate ...
Siderite is a widely distributed mineral, its composition is ferrous carbonate, when impurity of siderite ore is not many, can extract impurities as iron ore. Siderite ... Siderite Mine Steirischer Erzberg, Styria, Austria - brgm A new roasting technology in the process of ore -smelting was introduced.
Meanwhile, C/Fe mass ratio was elevated to 2.50 in the direct reduction of siderite to generate semi-coke as by-product, which contained 76.11% fixed carbon. Based on the characterization of the semi-coke, it can be used as solid fuel in the iron ore sintering to replace coke breeze and cut production cost.

9/29/2012· The chemical composition of the sinter obtained without Bakal siderite concentrate in the batch is calculated. The influence of Bakal siderite in the batch on the sinter composition is assessed. The sinter content in the blast-furnace batch, the MgO content in the slag, the slag yield, and the slag basicity are plotted against the content of siderite concentrate in the sintering batch.
Siderite FeCO 3 48.3 Taconite Wide variety of iron-bearing rocks, usually 20 to 40% (actual) Jaspilite Contains magnetite or haematite. * Assuming no impurities present in the ore For example, Australia's main iron ore deposits are predominantly haematite (Fe2O3) but …
The beneficiation of Deveci siderite ore by calcination and reduction processes was investigated in this study. Magnetic separation was applied to calcined and reduced ores respectively to ...
An investigation of the behavior of excluded siderite samples derived from both pure mineral species and by density separation of pulverized coal samples was conducted at combustion temperatures of 1100 and 1600 °C. Analysis of quenched combustion residues collected from the combustion gases under oxidizing conditions was obtained via scanning electron microscopy (SEM) with energy dispersive ...
In the present study, calcination properties of Hekimhan-Deveci siderite (FeCO3) ore and the effect of calcination process before the pelletization on strength of pellet were investigated and evaluated. Two different calcination processes were followed. One of them is the traditional calcination process and the other one is microwave assisted calcination process which is a new process for ...

During sintering, the fine ores are first mixed with additives and fine coke. This mixture then passes through a funnel onto a circulating moving grate. Ignition flames then set the mixed coke on fire. Due to the high temperatures, the ores "bake" together to a sinter cake (called sintering). Air vents provide a suction effect ("chimney ...
