At the iron ore area (FEOA, n = 8) we collected bats from the species Artibeus lituratus, and at the aluminum ore area (ALOA, n = 8) we collected bats from the species Sturnira lilium.The species selection was based on the …
The mill scale was used to prepare iron metal powder of 98% purity by reducing carbon monoxide gas (CO) at 1050°C for 3 hrs. Hydrogen reduction reduced carbon and oxygen contents to acceptable values (0.23% and 0.28%) [8]. Recently, the mill scale was converted to sponge iron through reduction by coke at different temperatures and times.
From ore processing to alloy design, the journey of iron through blast furnaces, direct reduction plants, electric arc furnaces, and continuous casting molds shapes the steel industry's strength, versatility, and sustainability.

Aluminum is used for a variety of applications from soda cans to airplanes, signs to automobiles. What you may not know is that these everyday items basically started with dirt. Mining. The type of dirt I am talking about is bauxite ore. …
I have several pieces of cast iron - roughly 5" x 1 1/2" x 1". I need to take the 1" dimension down to 9/16". I have a lathe and a small bench mill (Benchmaster). I am new to machining and have only worked with aluminum and a little bit of steel so cast iron is a bit of a mystery. What is the fastest way to take off this much?
Ball milling of the iron ore at 300 rpm for varying times – from 30 to 330 min – was studied to determine the effect of milling time on methane conversion. ... Various catalysts have been used in CMP studies, including solid metal and carbonaceous catalysts and, molten salts and metals [13, 18, 20, [27], [28], [29], [30]].
The mill scale contains high amounts of Fe and low amounts of silica and alumina. Thus, recycling it through the sintering process helps in the saving of raw materials like iron ore and limestone. This paper presents preliminary findings of a study that investigates the potential for recycling steel mill scale in the sintering process.
Treating ore by milling is generally a two-step process, first the ore must be crushed, then the crushed ore must be treated to separate the valuable mineral content from the waste rock. ... Stamps were akin to using a mortar and pestle …
