The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas. This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: [2CuFeS_2 + 2SiO_2 +4O_2 rightarrow Cu_2S + 2FeSiO_3 + 3SO_2 label{1} ]

Definition: A separation is a process that divides a chemical mixture or solution into two or more distinct product mixtures. A separation process may completely separate a mixture into its pure constituents in certain cases. Separations take advantage of differences in chemical or physical properties.

Figure 3. Filtration apparatus. Filtration procedure: 1) the mixture is pored through a funnel lined with a filter paper, 2) the filtrate (liquid) drips through to the filter flask, 3) the solid remains in the funnel. Though chromatography is a simple technique in principle, it remains the most important method for the separation of mixtures ...

Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

Using the ChemDraw Template provided, fill in the missing steps and structures. In each step, be sure that all necessary reagents and manipulations are included in their proper order.

Chemical Reduction. Carbon (as coke or charcoal) is cheap. It not only acts as a reducing agent, but it also acts as the fuel to provide heat for the process. ... Sometimes this can be removed afterwards (for example, in the extraction of iron); sometimes it can't (for example in producing titanium), and a different method would …

Model Answers. 1a 1 mark. A list of techniques used to separate mixtures is given below. fractional distillation. simple distillation. crystallisation. filtration. diffusion. From the list choose the most suitable technique to separate the following:

The reduction of iron oxides takes place according to the following chemical equations: Fe2O3 Fe2O3 + 3CO + 3H2 → 2Fe → 2Fe + 3CO2 + 3H2O (1) (2) (1) F e 2 O 3 + 3 C O → 2 F e + 3 C O 2 (2) F e 2 O 3 + 3 H 2 → 2 F e + 3 H 2 O. In contrast to the blast furnace process, the direct-reduced iron process operates at temperatures of up to ...

Overall reaction: HCl(aq) + NH 3(aq) NH + 4 (aq) + Cl − (aq) Then 5 drops more of 6M NH 3 are added after the HCl has been neutralized to make a mixture of NH 3 and NH + 4 that maintains pH ~9 and OH - at around 1 x 10 -5 M. The group III cations precipitate at this stage as hydroxides, as shown in Figure 5.1.1, except Ni2 +:
