So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.
How can I see only citations to my article?
After searching the name of your article, you can see the references to the article you selected as soon as you click on the details section.

Abstract:

Kuzeybatı Anadolu`da Çanakkale-Balıkesir Bölgeleri içinde kalan bazı halloysit ve halloysitli kaolen yataklarının yüksek alan şiddetli yaş manyetik ayırım ve özütleme yöntemleri ile zenginleştirmeleri araştırılmıştır. Birincil kirlilik kaynağı olan limonitlerin uzaklaştırılmasında en etkili işlemin özütleme olduğu, ancak ince taneli muskovitin ortamdan uzaklaştırılamadığı düşünülmektedir. ütlemede organik ve inorganik asitler araştırılmış, her iki asidin de başarılı olduğu bulunmuştur. ütleme işleminde en önemli parametrenin sıcaklık olduğu (80 °C), düşük sıcaklıkta (25 °C) yüksek asit derişimlerinde bile ayırım yapılamadığı anlaşılmıştır. Kinetik testler, organik bir asit olan oksalik asidin çalışılan her cevherde daha etkili ve daha hızlı bir çözücü olduğunu göstermiştir. TEM analizleri ile halloysit numunesinin nanometre boyuttaki tanelerinin özütleme ile bozunmaya uğramadıkları belirlenmiştir. Anahtar Kelimeler: Halloysit, kaolen, zenginleştirme, özütleme, manyetik ayırım In this study concentration of halloysite and halloysite/kaolin ores from northwestern Anatolia was investigated by wet high intensity magnetic separation and acid leaching methods. It was found that the acid leaching is the most effective method for the removal of primary coloring impurities such as limonite. However it is considered that fine grained muscovite cannot be removed from the ores even in the highest acid concentrations. In the leaching tests organic and inorganic acids were tested and both of them are found successful. It was concluded that temperature (80 °C) is the most critical parameter in acid leaching of iron from the ores since the separation could not be performed in the highest acid concentrations at low temperature (25 °C). It was realized that oxalic acid is more effective in terms of leaching kinetics and acid consumption. The morphology of raw ore and leaching concentrates of the halloysite samples were examined and compared by TEM analyses. It is understood that acid treatment process has no obvious effect on tubular structures. Keywords: Halloysite, kaolen, beneficiation, leaching, magnetic separation
