Copper extraction by wet chemical method
(Elsevier, 2018-07)
In many countries large deposits of copper with no locally established copper based industries occur because
known methods for extraction are prohibitively expensive and unaffordable. This study reports on an affordable
and ...
Properties of activated blended cement containing high content of calcined clay
(Elsevier, 2018-08)
This paper presents findings of an experimental investigation on sodium sulphate
(Na2SO4) activated calcined clay e Portland cement blends in sulphuric acid media.
Calcined clays were blended with Ordinary Portland Cement ...
Equilibrium Studies for Adsorption of Zn2+ on to Acid Treated Kikuyu Grass Pennisetum Clandestinum Biomass
(2016-04)
The feasibility of using Pennisetum clandestinum biomass as low-cost adsorbent for the removal of Zn2+ was
investigated in batch studies. The Freundlich, Langmuir,Dubinin Raduskevich and Temkin adsorption isotherms were ...

Magnetic Concentration of Iron in Lateritic Soils from Kamahuha, Murang’a County, in Kenya using Carbon Monoxide Generated In-Situ
(IJSET, 2014-08)
Chemical and Mineral Analyses of laterites from
selected sites in Kamahuha area of Murang’a County, in the
Republic of Kenya, have been carried out with particular
interest in the levels of iron and the type of minerals ...
Diffusivity of Sulphate Ion in Selected Ordinary Portland and Portland Pozzolana Cements Mortar
(Kenya Chemical Society, 2014)
Cement is subject to degradation by aggressive media. This study investigated sulphate
diffusivity in mortar made from selected Kenyan cements which included three brands of
Ordinary Portland Cements (OPC) and three ...
Determination of Potassium Levels in Intensive Subsistence Agricultural Soils in Nyamira County, Kenya
(2013)
Assessment of potassium levels in agricultural soils of Nyamira County, Kenya was necessitated by the observed progressive drops in maize acreage yields over the years despite use of phosphorus and nitrogenous fertilizers. ...
Beneficiation of Iron in Thermal-Reduced Ilmenite by Magnetic Separation
(2013)
ncreasing demands for Iron in countries development, and lack of conventional reducing agents has resulted into sourcing
of alternative ways of beneficiating the iron ore. This paper reports on the study that was done ...
Cementing material from rice husk-broken bricks-spent bleaching earth-dried calcium carbide residue
(2012)
A cementious material, coded CSBR (Carbide residue Spent bleaching earth Broken bricks and Rice husks), was made from dried calcium carbide residue (DCCR) and an incinerated mix of rice husks (RH), broken bricks (BB) and ...
Concentration of Laterites Using Biomass
(Kenya Industrial Property Institute, 2015-06-11)
A method of concentrating iron in laterites to make the iron extraction process economical
is disclosed. Concentration using biomass yields higher levels of iron by using appropriate
ratio of biomass: laterites. The ...
