Barite प्राथमिक छ, स्वाभाविक निरन्तर, बारियम आधारित खनिज. बारियम, परमाणु नम्बर 56, बाट ग्रीक यसको नाम derives र भारी अर्थ. Barite पनि baryte रूपमा जानिन्छ. barite को व्यावसायिक जम्मा हाल छन् जसमा प्राथमिक देशहरूमा संयुक्त राज्य अमेरिका हो, चीन, भारत र मोरक्को. Barite उच्च घनत्व र रासायनिक inertness यो धेरै आवेदन एक आदर्श खनिज बनाउन.
barite लागि रासायनिक सूत्र BaSO4 छ. यो एक उच्च विशिष्ट गुरुत्व छ 4.50 G / 3 सेमी. यसको Mohs कठोरता छ 3.0 गर्न 3.5. Barite, जो पहेलो सहित रंग को एक किसिम मा पाउन सकिन्छ, खैरो, सेतो, नीलो, खैरो, वा बेरंग, सामान्यतया चमक मोती एउटा काँच समान छ.
Barite धातु र Nonmetallic खनिज जम्मा दुवै संयोजनमा पाउन सकिन्छ. निकासी लागि आर्थिक कारगर हुन, barite सामान्यतया जम्मा मा प्रधान सामाग्री हुनु आवश्यक छ. यो सामान्यतया पाइन्छ जसमा जम्मा प्रकार नस समावेश, अवशिष्ट, र bedded. नस र अवशिष्ट जम्मा hydrothermal मूल को हो, जबकि bedded जम्मा sedimentary छन्.
संयुक्त राज्य अमेरिका मा प्रमुख जम्मा Georgia फेला गरिएको छ, मिसौरी, नेवादा र टेनेसी. क्यानडामा, खनिज को युकोन क्षेत्रमा mined गरिएको छ, नोवा स्कोटिया र न्यूफाउन्डल्याण्ड. मेक्सिकोमा, barite जम्मा हर्मोसिलो मा पत्ता गरिएको छ, प्युब्लो, मोन्टेरेरी र डुराङ्गो.
The overwhelming majority of the barite that is mined is used by the petroleum industry as a weighting material in the formulation of drilling mud. Barite increases the hydrostatic pressure of the drilling mud allowing it to compensate for high-pressure zones experienced during drilling. The softness of the mineral also prevents it from damaging drilling tools during drilling and enables it to serve as a lubricant. The American Petroleum Institute (एपीआई) has established specifications for the use of barite in drilling mud.
Dry Barite Beneficiation
STET has both pilot scale and commercial experience processing barite to remove gangue such as silicates, फलाम, and alumina. Low-grade barite beneficiation with a specific gravity between 3.5 - 4.0 has been successfully upgraded using the STET process to product API-grade barite.
STET can demonstrate that the dry electrostatic separation process offers many advantages over traditional wet processing methods (flotation) सहित:
Disrupting a new industry is always a challenge. ST उपकरण & Technology and Ramadas Minerals Pvt. लिमिटेड. in India understand this challenge well. Ramadas Minerals contacted STET to perform testing of a low grade barite / quartz sample produced at the APMDC barite mine in Andhra Pradesh, भारत. The material was a low grade tailings product from the mining process. It contained too much silica to be sellable as a high SG barite product, and was being produced in large volumes. What was needed was a process to transform the mining waste to usable product. Wet processing (flotation) was one alternative technology being considered.
Testing at the STET pilot facility demonstrated excellent separation results for the barite powder. The STET separator was able to achieve the goal of +4.20 SG barite through a single separation step.
The STET separator was fit into the existing building, which was originally designed to house a flotation facility. The STET separator installation resulted in significant savings of space, in relation to the previously designed flotation facility. साथै, a substantial reduction in capital and operating cost was realized.
