As the crisis of governance around iron ore mining in India demonstrates, the counterfactual is true, and administrators operate within a complex web of drivers and pressures. Although the doctrine of public trust is invoked by the courts regularly, it is yet to be fully examined and understood as a normative concept in Indian jurisprudence. The limited scholarship on the doctrine thus far

Crude steel production begins with the reduction process, whereby iron ore reacts with carbon sources inside the blast furnace. It is imperative that refractory products used inside the blast furnace are resistant to these thermomechanical and thermochemical reactions.

In India, where iron ore processing is one of the major industries, the generation of tailings is estimated to be 10-25 % of the total iron ore mined, amounting to 18 million tons per year (Das et al., 2000). The tailings contain silica in high percentage (40-60 %, from various locations). This makes it a suitable raw material for the development of ceramic tile compositions.

This work deals with the development of a ceramic colorant for glazes from an untreated iron ore residue. 6 mass% of the residue was added in suspensions (1.80 g/cm 3 density and 30 s viscosity) of white, transparent and matte glazes, which were applied as thin layers (0.5 mm) on engobeb and not fired ceramic tiles.

Dry processing at Vale. In the last 10 years, Vale invested almost R$66 billion in facilities and development of technologies for the dry iron ore processing production. Today, most of our iron ore production (about 60%) is through dry processing. The natural moisture processing is used at Carajás and Serra Leste mines, at S11D Eliezer Batista

The regeneration of the ceramic filter medium used in iron ore dewatering is often done by combining backwashing, ultrasonic cleaning and chemical regeneration. Of these three, the first two are applied more frequently, whereas chemical regeneration is done only when needed, eg once a day. Chemical regeneration of the ceramic filter medium in iron ore processing can involve the use of oxalic

The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced

Especially in iron ore processing, where low and even cake moisture content is crucial for the following pelletisation, the performance of the filter medium is vital to achieving this goal. In addition to blocking by slurry particles, crystallisation of solutes during the cake drying process can introduce more adhesion between the particles and the filter media[5].
