Self-build housing methods have been widely used in traditional western Nigeria in housing development. Recently however, there has been a shift to other westernize concepts of housing development which are observed to be more capital intensive than the traditional methods. While these westernized concepts are beneficial to the few high income earners, the urban poor who are in the majority are...

Dependence and interaction between several operating conditions that affect the grinding process using a ball mill such as number of balls, duration, rotational speed on particle size at 80% product mass (P80) mineral liberation have been obtained in this study CCD (central composite design) response surface method (RSM). The was carried out cylindrical with diameter length 18.6 cm 21.5 cm, res...

In the present study, leaching behavior of scandium from limonitic laterites under sulfation roasting–water (SAL) was explored. The mineralogical analysis showed that associated with iron phase. roasting temperature played an important role in phase conversion during process. With increase 100 to 800 °C, (goethite, magnetite, and hematite) gradually converted monoclinic Fe2(SO4)3 (400 °C), then...

In order to achieve the effective utilization of limonitic nickel laterite for stainless steel production at lower cost, distinct difference in high-temperature characteristics between and ordinary limonite has been systematically expounded via compact sintering method comparative analysis relevant performance suitable basicity also conducted through sinter pot tests. The results indicate that ...
