This paper presents the results of experimental and analytical studies mechanical thermal properties laterite composites mixed with reprocessed low-density polyethylene waste (LDPE), calcium phosphate (CaP) phosphogypsum wastes, biochar to form brick composites. Bricks mixtures 20% by volume LDPE, 15% CaP, gypsum were shown have excellent compressive strength, flexural fracture toughness. The 1...

In the present article, adsorbent prepared from laterite with lanthanum and cerium oxides (La2O3-CeO2/laterite (LCL)) was efficiently employed for removal of arsenite fluoride an aqueous environment. The obtained materials were characterized by XRD, SEM, nitrogen adsorption/desorption. synthesized LCL exhibited a high adsorption capacity towards (As(III)) fluoride. both analytes on LCL, which w...

A high amount of energy is required to produce different types clay and sand-lime bricks, a huge carbon dioxide released into the atmosphere. Also, brick waste from destruction dilapidated buildings pollutes environment. Application pozzolanic sources containing aluminosilicate alkaline activators can be beneficial in production geopolymer which do not need baked furnace recycled. laterite-base...

Abstract Interest in low-grade Ni-laterite ores has increased recent years; however, the laterite process proven technically difficult and costly, development of alternative low-cost biotechnologies for Ni solubilization been encouraged. In this context, first time, a sample Brazilian ore was subjected to microbial bioleaching using heterotrophic Burkholderia sp. strain. Experiments were perfor...
