The manganese ore is the main raw material to the ferroalloy production. During its beneficiation, fines are produced and were placed in tailing dams. An alternative to the material that is dumped in tailing dams is to agglomerate it in form of briquettes. When charged inside the submerged arc furnaces, the briquettes must have enough strength in order to maintain its size and shape. Unless the agglomerates would behave as the unwanted fines undermining its performance. Thus, the work has as subject the study of the parameters that influence the compressive strength on briquettes made of manganese tailing dam material and cement. The work is based on the hypothesis that there is a set of parameters for such materials which maximize the compressive strength. This work has as objective assess the impact of curing time, rate water/cement and top size of the raw materials in the compressive strength of briquettes made of manganese ore fines and cement. To fulfil the objective, briquettes with a mass percentage of cement of 10 % were produced. To find the influence between the rate water/cement agglomerates with rates of 0,5, 1 and 1,25 were produced. To assess the impact of curing time, specimens were produced and cured for 1, 7, 14, 21 and 28 days. To measure the effect of different raw materials top size, briquettes which the top size was 0,250, 1,00 and 2,00 mm were produced. The results showed that the best set of parameters to increase the compressive strength to the an optimal is rate water/cement of 1, curing time of 21 days and raw materials top size of 1,00 mm.
