I was fortunate to attend the school in 1971/72 whilst working as a metallurgical engineer on the Bougainville Copper Project that was being constructed. Professor Lynch and Bill Whitten certainly were great motivators for a young process engineer with the breakthrough work they were doing at that time.

Let us congratulate Barry for bringing three generations of Mineral Engineers to the same platform.<br /><br />I must compliment you all for following Barry's Blog which is so informative, informal, relevant and probing. Barry, keep motivating the next generation, this will pay rich dividends to the knowledge and practice of the technology. I am happy that the 'sapling' Rao took to India from Australia has been planted at the right place, i.e. ISM, and the tree is growing strong and healthy. This is what I gathered after reading the comments by your Director Dr. Panigrahi. It was good of him to express those feelings about Rao and Barry in spite of his busy schedule. It also shows the importance given to Mineral Engn at ISM. There are many challenging issues which require first class research and their solution will contribute much to industry in the area of Mineral Engn. The industry has become more global now and I am sure all of you will do very well and play your rightful role with the strong fundamental knowledge of Mineral Engn you must be getting at ISM. I extend my best wishes to all of you.<br />Alban Lynch, BrisbaneAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-82291471976436576572014-08-20T09:24:49.005+01:002014-08-20T09:24:49.005+01:00Thank you, Suzy; I still remember those times--dea...Thank you, Suzy; I still remember those times--dealing with the tough task master (Your father at work) and the most exciting and pleasant working atmosphere I used to have in J.K.Centre(your father as Director); the very happy and most enjoyable homely atmosphere me and latter along with Girija, we used to have at your home with the motherly and gentle touch of your mother.<br />Bless you all.<br />Rao,T.C., India<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-84891719924214665012014-08-19T08:43:29.431+01:002014-08-19T08:43:29.431+01:00Mineral Engineering is a unique branch of study re...Mineral Engineering is a unique branch of study related to mineral industry. Unless one undergraduates at this, he or she would not be aware of the role of a mineral processing in the gamete of mine to metal. Keeping this in mind, it is at times difficult to feel inspired due to the lack of mainstream recognition that the other core branches of Engineering usually have. In Asia, if not in the entire world, Indian school of Mines (ISM) is the only Institute to feature an undergraduate Department of Mineral engineering. Therefore, the students in this branch at times feel lost to grasp the effective role they can play both in the development and practice of Mineral Engineering. The profile of Prof. Alban Lynch is a typical example and an immense source of inspiration of a man who has dedicated his life in developing the subject - MINERAL ENGINEERING.<br /><br />In this regard, the blogs of Dr. Barry Wills appearing in the MEI website, highlighting the Profiles of Prof T.C. Rao followed by Dr A J Lynch (a rare combination of a teacher and the student) sequentially, is a source of inspiration to all the students of Mineral engineering, at ISM. Both of them stand as founder members of Mineral Processing in their respective countries. The point to be noted is, Dr Barry Wills, another visionary, who could gauge these facts and made the world to be aware of it. Through these profile descriptions, initially of the student (Prof T C Rao) and then of his teacher (Dr Alban Lynch), Dr Barry cited how teacher-student collaboration could be effective and fruitful in the long term for the development of a subject. <br /><br />Although we do not know both of them (except seeing Prof Rao during his seminar/ conference presentations), but through this blog we could witness that transition of these men from the stature of hard working and passionate students to eminent figureheads, pioneered in many of the technical areas related to mineral Engineering. <br /><br />Dr. Barry not only made us proud but also inspired the younger generation being the leading figure in mineral engineering. Hats off to Dr Barry for being the path setter.<br /><br />Archit Mazumdar and Fellow Students of the Department of Fuel and Mineral Engineering, Indian School of Mines, Dhanbad-826004Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-19803084064803124362014-08-17T19:40:11.890+01:002014-08-17T19:40:11.890+01:00I'd better not comment on the cricket!I'd better not comment on the cricket!MEIhttps://www.blogger.com/profile/14834780351452765156noreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-64555758669035918642014-08-17T17:05:43.641+01:002014-08-17T17:05:43.641+01:00Many thanks Suzy.

As most of my brothers and sisters do not have access to this forum, I would just like to send my thanks to you on behalf of all of us for putting in writing (for us and our families) the things he has told us, or that we lived through with him, over the years. We well recall Prof T.C.Rao - he has always held a special place in our family, as has his wife and family. <br /> Your account is an excellent written record for when those memories fade over time and generations. <br /><br /> Best regards, <br /> Suzy Lynch-Watson.Metso Minerals, AustraliaAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-31764715462257395372014-08-16T11:53:41.216+01:002014-08-16T11:53:41.216+01:00Hydrocyclone and/or Heavy media cyclones separate ...Hydrocyclone and/or Heavy media cyclones separate particles based on the settling velocities and related velocity phenomena and fluid density.

In a precise form he has brought out all the relevant information which we need to know. Earlier he had written about Dr.T.C. Rao, a worthy student of Prof. Lynch and a true flag bearer of the concept initiated by Prof. Lynch, that an operating plant should be utilized to understand mineral engineering in action. Both these stalwarts have shaped the way of thinking of many of us who joined the profession in & around 1970s. While modeling & simulation may be spectacular developments but both these require a deep understanding of the process involved and the parameters affecting the process or the performance of an equipment. I believe the singular achievement of these two persons have in the emphasis that these equipment's have a behavior pattern of their own and the mineral engineer should understand this first and then dabble in modeling efforts. Since Dr. Wills is making such great efforts to make us acquainted with the life & work of great scientists in mineral field, may I also request him to write such well articulated documents on earlier mineral scientists like Prof.Gaudin & Prof.Hukki.

The simplicity and high capacity of a cyclone make it ideal for large scale operations, however we must scalp gravel out of the feed to a cyclone to avoid spigot blockages which could have disastrous consequences, placing a screen ahead of the cyclone to scalp out gravel from a cyclone feed is an ideal situation. <br />But the biggest advantage of a cyclone (if designed correctly) is its ability to reject coarse gangue, thereby increasing throughput and reducing grinding costs ( don't grind what you don't need to grind!!). <br /> <br />Enzo Artone, Principal Consultant at METOPS, AustraliaAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-66025709590545664652014-08-13T08:32:37.404+01:002014-08-13T08:32:37.404+01:00At least part of the preference for hydrocyclones ...At least part of the preference for hydrocyclones lies in the high throughput of modern concentrators. When you are processing 200 ktpd and grinding to a P80 of 200-300 microns with 200-400 % recirculating load in a grinding section, it would require a lot of screen area and there are related wear and maintainability concerns. <br /><br />These comments from Alban Lynch illustrate the critical necessity for research and development in mineral processing to include as a major part of their focus the industrial environment. <br /><br />Looking at mineral processing over the last century once could critically see much of the development in comminution, flotation, solid-liquid separation as being a case where the application as technology (including equipment sizing, flowsheet designs and other developments) has lead science, i.e., the practice of engineering where much depends on people-/team-related work. For us to ignore this aspect re pioneering and application is missing a major component of how mineral processing adds value (both from knowledge and economic perspectives). <br /><br />Thanks again to Dr. Lynch for the pioneering in this arena and demonstrating industrial operations are important sites for research work & that it is possible to do meaningful work at industrial operations. <br />Robert Seitz, Manager - Crush, Convey, Concentrator at Freeport-McMoRan Copper & Gold Inc., USAAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-80021677602232484902014-08-12T16:34:40.018+01:002014-08-12T16:34:40.018+01:00Sir, Professor B A Wills needs to be congratulated...Sir, Professor B A Wills needs to be congratulated for introducing us the Legends of Mineral processing.<br />BPRavi BPRavihttps://www.blogger.com/profile/17572736806085092274noreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-37999053679375638992014-08-12T16:27:19.357+01:002014-08-12T16:27:19.357+01:00A comment about the hydrocyclones' high recirc...A comment about the hydrocyclones' high recirculating loads made me curious about why industry seems to prefer hydrocyclones over screens.
