3 — Conversely a high stripping ratio means more overburden removal is required which can be economically detrimental and environmentally taxing Understanding and calculating the appropriate stripping ratio for a mining project is indispensable for planning and the long term sustainability of mining operations Stripping Ratio Calculation
WhatsApp
— In this study we investigated reduction of magnetite by H2 during microwave irradiation This process combines the advantages of microwave irradiation and using H2 as a reducing agent to mitigate CO2 emissions during the ironmaking process Weight change measurements showed that a reduction of 75% was achieved after
WhatsApp
— Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron II and iron III Its empirical formula is Fe 3 O 4 and it is often expressed as iron II III oxide In the past it has been called ferrous ferric oxide and triiron tetraoxide Magnetite is found in igneous metamorphic and sedimentary rocks
WhatsApp
— The stripping ratio of a deposit may be used in part to gauge how profitable it may be The lower the strip ratio the better as a low strip ratio translates into a lower mining cost said Cormark Securities mining equity research analyst Stefan Ioannou For instance a project with a very high strip ratio likely will not be profitable
WhatsApp
— Stripping ratio can refer to the entire reserve or a particular mining stage Units can be weight or volume imperial or metric even linear measurements of depth The SG of waste usually differs from that of ore Care must be taken to properly compare like with like Stripping ratio worsening as ore reserve thins Stripping ratio worsening as
WhatsApp
— Magnetite is a remarkable material with unusual properties and diverse applications Probably the best known example is magnetite iron ore used for steel production which consumes millions of tons per year Another lesser known use is in water purification where very high purity magnetite is used as a feedstock to produce iron
WhatsApp
— Magnetite nanoparticles for biomedical applications are typically prepared using the coprecipitation technique which is the most convenient method However the reaction pathways leading to the production of the magnetite phase in the coprecipitation reaction are not fully understood despite the fact that the reaction path may be of
