dry grindability of Kfeldspar in the stirred ball mill were also analyzed. 2. Experimental Equipment The HD01 model laboratory scale vertical stirred ball mill, used in both dry and wet milling modes, was developed by Union Process (USA) (Figure 1). This model ball mill is designed for use at stirrer speeds
The albitization of Kfeldspar is a common diagenetic process that has thus far received little attention and is not fully understood in finegrained sedimentary rocks. To better understand the albitization of Kfeldspar, studies in organic and siltrich finegrained rocks of the lower Cambrian Qiongzhusi Formation in the southwestern Upper Yangtze region, China, were carried out via Xray ...

Feldspar (sometimes spelled felspar) is a group of rockforming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. [3] The most common members of the feldspar group are the plagioclase (sodiumcalcium) feldspars and the alkali (potassiumsodium) feldspars. [4]

The chemical composition of feldspars includes alcalic metals, aluminum, silica and oxygen. The general chemical formula is a bit complicated (K,Na) 1x (Ca,Ba) x (Si 3x Al 1+x O 8).This complexity is caused by presence of both monovalent and divalent cations which require more complicated heterovalent substitution.
The chemical analysis of the raw materials is provided in Table the chemical analysis, it is seen that BOF and BF slag contain higher amount of alkaline earth oxides (CaO and MgO) which will act as an auxiliary flux in addition to the alkali minerals (K 2 O and Na 2 O) present in feldspar. The presence of higher amount of Fe 2 O 3 in BOF slag will also promote the vitrification.
Pseudomorphic replacement of feldspars (plagioclase, perthitic alkalifeldspar, redstained Kfeldspar) at Olympic Dam commonly results in microscale intergrowths of sericite + Feoxide assemblages, within which a variety of other mineral species can also be present (KontonikasCharos et al., 2017a).

Feldspar is the general term for minerals in the feldspar group. It is a common type of aluminosilicate rockforming mineral containing calcium, sodium, and potassium. Feldspar has a glass luster and various colors. It accounts for up to 60% of the earth's crust and can appear in igneous rocks, metamorphic rocks, and sedimentary rocks.
Order of feldspar roasting was found to be around 2, and activation energy requirement was kJ/mol. Calcium and sodium were leached along with potassium from chlorideroasted KFeldspar with ...
In feldspar, K + balances charges, releasing two potassium ions for every Ca 2+ during extraction. ... The ceramic mill was chosen for the grinding step to avoid contaminants. The grinding process used a 60% solid ratio with a 40% ball charge. The feldspar sample with a size of less than 106 microns was used in all of the experiments.
