To investigate the flexural performance of high titanium heavy slag concrete composite beams under loading this study examined the impact of various factors on deflection development and crack propagation as well as the applicability of empirical formulas for monolithic concrete beams Seven concrete beams were fabricated with variables such as the
A direct reduction magnetic separation alkali leaching dilute acid washing method was proposed to prepare high quality acid soluble titanium slag HQASTS from titanium middling ore The relevant potential pH diagrams were built and the analysis results showed that the pH values for alkali leaching and dilute acid washing should be higher than and lower
Materials 2020 13 1239 2 of 12 4% in the cementitious materials the best result increased the compressive strength of the cement mortar after 28 d from MPa to MPa which is an increase
Compared to other titanium slag recycling processes the alkaline leaching proc ess is relatively mild and high recoveries are obtained at relatively low temperatures and atmospheric pressure
A plant in Australia processes ilmenite placer ore The titanium in the ore is mainly ilmenite followed by rutile white titanium brookite and sphene % of titanium is dispersed in iron manganese minerals goethite pyrite hydrohematite etc and gangue minerals kaolinite quartz feldspar etc
To achieve high efficiency low consumption clean and high value added recycling utilization a new process is proposed herein which entails reacting a CH 4 H 2 N 2 gas mixture with the titanium bearing blast furnace slag to initially produce Ti C N O at a low
This paper presents a brief review of the history of titanium smelting and the current trends in related research and development Presently both electrolytic and metallothermic reduction processes utilizing various feed materials such as titanium oxide are widely studied However many challenges remain to be addressed before realizing the
Electric furnace smelting has become the dominant process for the production of the titanium slag from ilmenite in China The crystallization behaviors of anosovite and silicate crystals in the high CaO and MgO titanium slag were studied to insure smooth operation of the smelting process and the efficient separation of titanium slag and metallic iron The crystallization behaviors were
experience of coal ash and slag recycling but at enormously lower percentage as compared to dumping For example since 2017 the Novokuznetsk power engineers execute a mining area reclamation project at a closed mine in Ordzhonikidze district The project uses ash and slag from the Kuznetsk CHP Power Plant with a view to preventing landslide and
For several decades the metallurgical industry and the research community worldwide have been challenged to develop energy efficient and low cost titanium production processes The expensive and energy consuming Kroll process produces titanium metal commercially which is highly matured and optimized Titanium s strong affinity for oxygen
The total cost of comprehensive processing should be lower than the created value after resource collection and utilization which indicates that the recycling process should be simple feasible
Brazilian plastic recycling plants directory showing companies in Brazil that process plastic waste into new materials 161 plastic recycling plants based in Brazil are listed below Plastic Plant Brazil
tions nitric acid plants and some organic synthesis production Upgraded titanium slag UGS is one of the fundamental Minerals 2021 11 1425 6 of 21 high purity titanium low purity
The electric arc furnace steelmaking route is essential for sustainable steelmaking through hydrogen based direct reduced iron About 30% of the global steel production currently follows the scrap/direct reduced iron electric arc furnace DRI EAF route which is bound to increase given decarburization efforts by the steel industry We investigated
the slag decreased and the content of perovskite phase in the slag increases with the increase of TiO 2 content Although the influence of TiO 2 and basicity on the viscosity of slag has been widely researched 9 much less attention has been paid to ultra high titanium slag from the perspective of heat input
REMONDIS Production uses wet mechanical technology to separate high alloyed metals at the Lippe Plant the only site able to do this in Europe Why process metal slag at all Recycling metal slag is also good for the environment Processing this material creates both environmental and economic advantages as it prevents the rare and
In this work a strategy of heat treatment precipitation has been developed to recycle Ti containing metallurgical solid waste by forming Ti embedded MgAl layered double hydroxide TMA LDH This facile and simple route is featured by the dedicated utilization of the composition of slag with high overall recovery efficiency Importantly as obtained product
Titania slag represents an important feedstock for the manufacture of titanium dioxide pigment by the sulphate process Moreover part of the pro duction of the titania rich slag is further acid leached under a high pressure and moderate temperature hydrometallurgical process to yield an upgraded titania slag with mass percent TiO 2 which
Fig 7 d shows the simulated recycling degree for titanium metal There is no titanium dioxide recycling and everything used is lost The metal recycling spikes up when the metal production stops and because a sharp increase in metal price Fig 7 e shows the simulation of price for TiO 2 and titanium metal Fig 7 e shows the metal and TiO 2
The titanium rich slag was produced from the low grade ilmenite concentrate the low TiO 2 content and the high content of impurities During the production of the high grade titanium slag TiO 2 content 75 80% the impurity elements are transferred into the associated alloyed metal cast iron Thus it can be used to smelt the steel
It is obvious that recycling of titanium scrap is necessary and according to statistics the cost of titanium alloy ingots will be reduced by % for every 1% of titanium added after the
The main raw material for these technologies is high titanium slag and/or rutile obtained from ilmenite concentrate The most popular method for producing titanium slag is reduction melting in electric furnaces at a temperature of 1600 1700 C during which iron oxide is reduced to metal
