Water management


In the process of extracting and transporting raw material from existing mines in dry areas, it is common to move a lot of dust due to the movement of transport trucks. This is a risk to operational safety - drivers, auxiliaries and other workers - who work in the extraction and transportation activities, as well as potential negative impacts on the environment and workers’ health caused by excess of dust. Currently, to control / minimize these impacts, it is common to use a water truck to wet the roads. However, this process is costly due to the long distance traveled to fetch water and also due to the scarcity of this resource in dry regions. Moreover, due to elevated temperatures, this process is repeated several times so that it becomes inefficient soon after it is done because all moisture is lost rapidly. Therefore, solutions are sought to reduce the dust in the roads with greater efficiency, at lower water consumption and lower costs.

Water Management

Quantitative and Qualitative Monitoring

Develop solutions to reduce moisture in the production chain (Mine, Mill, Railway, Port) of hydrated iron ore. Highly wet ore is difficult to be transported, it generates loss of volume of iron transported from ports – by carrying an amount of water in the volume - and, finally, it must be controlled in order to guarantee the maximum limit of moisture established by TML during loading of ships. Currently, there is a drainage system during the process that involves draining in areas and in the railroad besides weather and moisture forecast to help in decision making. However, the final decision-making process on the transportation of the ore according to its level of moisture is only given at the port itself. Solutions are expected to reduce the moisture content of iron ore in the chain, to monitor it in a timely manner and to attenuate the dependence of this control on climatic factors.
